Open Ended Challenges GUIDE

### Description

Are you looking for challenging math problem solving tasks that keep your students engaged, apply the math you have taught, and meet the rigor of the Common Core State Standards? Now available with a DIGITAL COMPONENT as well!

This bundle is for you!

This set of 12 (4 sets of 3) math problem solving challenges can be used in a number of ways…as whole class explorations, as small group challenges, or as independent work for those students needing something more. In my classroom, these are often whole-class explorations where students work in teams, share ideas, guess and check their ideas—and then present their solutions. The problem solving and math applications are high level and meaningful.

Because grade 2-3 students may not have experienced this type of problems solving before, I have offered the tasks with different types of support. In some cases, I offer different levels of challenge. In other cases, tables and other organizers are provided to help students see what work needs to be done and to help with precision and accuracy.

**************************************************************************************

Appropriate for grades 2-3, depending on skill level and level of support offered or for grades 4-5 for review or for less experienced problem solvers. Selected answers are included, but many of the tasks (by definition of "open ended") have multiple solutions.

Don't let the "Seasonal" label stop you... I use these tasks all year--some teachers just like to tie some activities to the time of year--and these sets can help with that!

**************************************************************************************

Here are the 3 challenges in the winter set!

Skating Spectacular

This challenge asks students to solve a multiple step problem where they need to rent skates for a group of people, buy snacks, and then come up with a total cost. The task is available in “Level A” which has only whole dollars (ex. \$5) and “Level B” which uses money with decimals (ex. \$3.25). You can use either version for your whole class or you can differentiate within the class because the task stays the same no matter which set of numbers you use.

Snow Day Celebration

This challenge is all about time and students need to add amounts of time to fill a daily schedule. This is a great beginning to understanding elapsed time as well has how our non-base 10 time system works—that an hour can be divided into four equal parts of 15 minutes or 2 equal 30 minute parts. There are countless ways for students to plan their snow day, and the “rules” about limiting video games and so on add an addition challenge.

The cookie challenge is a fun one for students and can be accessed in a number of ways. Students could use manipulatives to model the pans of cookies. They could draw pictures. They could use repeated addition or even multiplication! This is a true open ended challenge because there are many ways to solve it—and then there are challenge questions at the end for students who are ready for a little bit more!

and the spring tasks...

Great Gardening

This challenge asks students to solve a multiple step problem where they need to use a given garden “array” to break the garden into smaller plots (arrays) to fit 5 different vegetables perfectly. There are multiple ways to solve this, and the questions that follow increase in difficulty. This task focuses on the concept of basic multiplication, basic perimeter, and addition of 2 digit numbers, including length.

A Day at the Zoo

This challenge is all about “time” and students need to use the rules given them for their day at the zoo to make sure they can see all the exhibits, take their zoo train ride, eat lunch, and watch a movie about endangered animals. Students need to be able to add amounts of time under an hour and plan their schedule for the day. The enrichment options following the main task add money and budgeting into the mix as well as some basic addition, subtraction, and multiplication computation work.

Baseball Budgets

It’s time for the team to get new uniforms! Students need to keep the cost per uniform to \$100 or less while making choices between different options. The focus on this task is adding multiple two digit numbers, but the task continues by using basic multiplication concepts and addition of larger numbers and money.

...summer

A Day at the Beach

This challenge asks students to plan for a day at the beach by purchasing supplies before the trip—and to solve some problems they encounter while they are there. It focuses on addition and money skills. The task is available in “Level A” which has only whole dollars (ex. \$5) and “Level B” which uses money with decimals (ex. \$3.25). You can use either version for your whole class or you can differentiate within the class because the task stays the same no matter which set of numbers you use.

Camping Cookout

This challenge requires students to plan a meal for a baseball team. They will need to figure out how much food by thinking about “groups” of food (repeated addition or multiplication) and then also to figure out the cost! This task requires lots of planning, organizing work, and adding or multiplying.

Festival Fun

The Festival Fun challenge asks students to use a set of information about tickets for a festival to find four DIFFERENT ways for a family to use their tickets. The task then also provides several other problem solving experiences as well.

...fall

Apple Picking Problems

This challenge asks students to help pack apples into bags of different sizes. Students may use addition strategies or basic multiplication to help them find a way (and there are many) to determine how many apples they have in all, how many small and large bags to fill, and how much money they will make I all. This is a complicated problem with multiple steps, but one that could be solved with manipulatives or paper and pencil.

Raking up a Storm

This challenge requires students to answer questions about three sisters who needed to rake up 18 bags of leaves. The task asks them to solve elapsed time problems, basic addition (including finding multiple solutions), and a basic division “sharing” problem. Please note that students may need coaching to understand that 30 minutes is a half hour and there are four “chunks” of 15 minutes in an hour.

Pie Making Party

The Pie Making Party problem asks students to take a set of information (slices per pie) to find a way to reach exactly 200. Students could use manipulatives, repeated addition, subtraction, or multiplication strategies to come up with a solution. After they solve part 1, there are additional challenges involving solving problems with money.

----------------------------------------------------------------------------------------------------

These problems are meant to take extended periods of time! Please allow students to work long enough to do high quality work! These problems often take 2-3 class periods...especially if you give ample work time, pull the class together to share ideas/troubleshoot along the way, share tips, and so on.

Remember, part of problem solving involves “problems!” so don’t expect these to be easy for your students who are used to getting a solution quickly—or who expect there to only be one “right” answer! Celebrate great ideas and strategies… sometimes the process is more important than getting a correct answer in the end! Common Core connection pages are included, but know that students may use a variety of strategies to solve these so they are just “connections” to help you with your planning.

### Standards

to see state-specific standards (only available in the US).
Attend to precision. Mathematically proficient students try to communicate precisely to others. They try to use clear definitions in discussion with others and in their own reasoning. They state the meaning of the symbols they choose, including using the equal sign consistently and appropriately. They are careful about specifying units of measure, and labeling axes to clarify the correspondence with quantities in a problem. They calculate accurately and efficiently, express numerical answers with a degree of precision appropriate for the problem context. In the elementary grades, students give carefully formulated explanations to each other. By the time they reach high school they have learned to examine claims and make explicit use of definitions.
Model with mathematics. Mathematically proficient students can apply the mathematics they know to solve problems arising in everyday life, society, and the workplace. In early grades, this might be as simple as writing an addition equation to describe a situation. In middle grades, a student might apply proportional reasoning to plan a school event or analyze a problem in the community. By high school, a student might use geometry to solve a design problem or use a function to describe how one quantity of interest depends on another. Mathematically proficient students who can apply what they know are comfortable making assumptions and approximations to simplify a complicated situation, realizing that these may need revision later. They are able to identify important quantities in a practical situation and map their relationships using such tools as diagrams, two-way tables, graphs, flowcharts and formulas. They can analyze those relationships mathematically to draw conclusions. They routinely interpret their mathematical results in the context of the situation and reflect on whether the results make sense, possibly improving the model if it has not served its purpose.
Make sense of problems and persevere in solving them. Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution. They analyze givens, constraints, relationships, and goals. They make conjectures about the form and meaning of the solution and plan a solution pathway rather than simply jumping into a solution attempt. They consider analogous problems, and try special cases and simpler forms of the original problem in order to gain insight into its solution. They monitor and evaluate their progress and change course if necessary. Older students might, depending on the context of the problem, transform algebraic expressions or change the viewing window on their graphing calculator to get the information they need. Mathematically proficient students can explain correspondences between equations, verbal descriptions, tables, and graphs or draw diagrams of important features and relationships, graph data, and search for regularity or trends. Younger students might rely on using concrete objects or pictures to help conceptualize and solve a problem. Mathematically proficient students check their answers to problems using a different method, and they continually ask themselves, "Does this make sense?" They can understand the approaches of others to solving complex problems and identify correspondences between different approaches.
Recognize area as additive. Find areas of rectilinear figures by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts, applying this technique to solve real world problems.
Solve two-step word problems using the four operations. Represent these problems using equations with a letter standing for the unknown quantity. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.
