FACT: Students need more practice solving subtraction problems. FACT: This collection has lots of subtraction problems. FACT: Not all subtraction problems are the same: some are "take away," some are "let's compare one with another," some are "I have something and took away this, now I have this...." This is a collection of over 200 different "BIG Busy Bee Hive" puzzles where students practice subtraction in a context that is fun and thoughtful. That is, yes, they get lots of opportunities to do

This is a set of 90 puzzles (30 at each level) of Advanced "Square Knot" Puzzles focused on practicing problems solving for 1st through 3rd graders using addition and subtraction. The format is the same as other square knot puzzles, with larger numbers. Why you should try these: One of the things that we should be emphasizing from the very earliest of ages is mathematics as problem solving. This is more than writing a bunch of word problems: problem solving is about using various techniques for

This is a set of 90 puzzles (30 at each level) of "Square Knot" Puzzles focused on practicing problems solving for early learners (1st - 3rd grade) using addition and subtraction. Why you should try these: One of the things that we should be emphasizing from the very earliest of ages is mathematics as problem solving. This is more than writing a bunch of word problems: problem solving is about using various techniques for finding the correct answer. In this set of puzzles, students have to arran

79 89 99 119? 129? Take 2: 134 124 114 84? 74? Do your students struggle to count by 10s across 100? If they're doing mental math, then they probably will at one time or another. So why not help them practice this so they don't say things like "75, 85, 95, uh, uh, 105?" This is a "three-fer" - you get the group game "roller coaster" where a group of students compete cooperatively to count up and down by tens between a bottom and top number. For example, the first students says 78, the next one

Are you sick and tired of drilling & killing your kids on the combinations of 10 and just saying, "okay, there's nothing fun about this, so let's just move on." Sorry, I've got to call BS on that. Because learning combinations of 10 is also an opportunity for your students to do some problem solving, do some algebraic thinking, as well as make many, many mistakes. These are NOT worksheets! They are puzzles and are designed to be "hands on" and "manipulative." That is, your students will work w

This is a collection of 9 different colorful Cuisenaire Rod "make the road" puzzles which challenges your students to cover a path using exactly one of each rod. Each one has a different colorful background. This is a great activity that your students can do independently during a work time or placed in a math center. There's a handy chart you can fill in with your students' names to keep track of which puzzles they've completed, with fillable form fields. There is also an option for students

This is a set of activities that focus on helping first and second graders memorize the doubles from 1 - 10, with special focus on the "hard doubles" of 7, 8 and 9. There are two different games, and 20 different puzzles involving "number searches" where students find a number and its double nearby. Students also practice writing doubling and halving equations. There is also a set of "locate and calculate" assessments where students locate a doubling equation and then record it.

This is a collection of 95, yes, you heard it correctly, 95 different "equation search" puzzles that target different kinds of computational strategies. There are actually 15 or so different puzzle types, with 6 different iterations (that is, same puzzle with different numbers.) So if your students need additional practice, you can have them do more of them. Actually, I've automated all these puzzles to generate random numbers, but that' another matter. For example, there is a search sheet where

This is a collection of 40 different hexagonal subtraction/additional/logic puzzle cards (hence, the title above.) It includes a solution recording sheet, so your students can do them in any order they want. These would be best used for advanced first graders (who want to tackle double digit addition), 2nd graders who are practicing single and double digit subtraction and addition, and assessing and remediating 3rd graders and above. What's nice about these puzzles is that they are "threefers" -

This is a collection of 8 different Thanksgiving Themed "matrix addition" puzzles which use funky symbols as clues to figure out the answers. They were designed for 2nd graders, but you could use them with advanced first graders, or just throw them at some third and fourth graders to see how they react. They're sort of algebraic puzzles that you can have a lot of fun with and who doesn't like fun? Comes in color and b/w for your printing pleasure! What makes this really cool is that I also in

Greetings teacher phrens, Here's the activity you've been waiting for if you want your students to become more flexible and fluent with non-routine number facts and combinations using MENTAL MATH STRATEGIES; Schools o' Fish challenges students to take 15 different numbers and arrange them in groups so that they add up to the same number (at least, in this version.) Features: • EZ Cut n' Paste Technology: the pieces have been arranged in such a way that your students can cut out all 15 in abo

This is an activity which extends the TERC Investigation "Peas and Carrots," which is a very nice investigation, but ends way too soon. So I upgraded it by turning it into a detective game: students take a stack of cards which use different number combinations of the same two items (11 beans and cornbreads, 10 platypodes and penguins, etc.) Students take the stack of cards, remove one from the deck, and then look at the other ones to figure out which one is missing. Along the way, students lear

Great for math centers! This is 20 different "addition tower" problems: it combines Basic Set of Addition Towers and adds 10 more puzzles that use various combinations of digits to make the totals located at the base of each tower. Cut out the digit cards and place them directly on to the puzzle sheets until they get a solution and then record them on the answer sheet. Includes recording sheets so that you don't have to print up individual sets for each student, and a "DIY" sheet so that you

Here's a cool idea: give kids a set of numbers 1 - 10 and have them place them in columns so they add up to a number at the bottom of the tower. Great for practicing addition fact combinations, as well as developing problem solving skills. This is a basic set of 10 puzzles that is appropriate for K - 2nd graders. Great for math stations! Not so good for "scoot," because different kids will need different amounts of time to solve. Includes solutions AND a "do it yourself" template so you & your

Yep, you read it right: 100 Questions for the 100th Day of School - it's 10 pages, numbered 1 - 10, 11 - 20, yadda, yadda, yadda. The questions vary between things like estimating ("How long would it take you to draw 100 stars?" to counting ("What's the total number of tally marks? How many more would have to make to get to 100?") to complements of 100, and all sorts of interesting facts about 100 (for example, that a googol is a 1 followed by 100 zeroes....) I've used this with first through

This is a collection of 24 different puzzles that challenges your students to find the coin combinations in a piggy bank. There are 8 pages of cards, with 3 puzzles on each card, in both glorious black/grey/white and pastel colors (pink and chartreuse.) Cut out the 24 different cards, laminate and then put out for your kiddos to solve. Lower number cards are easier, higher number cards are tougher. They can solve by putting the coins into the circles printed on the cards. You can check students

This is a collection of task cards where students are given two clues about what coins are inside the piggy bank: the first is the value of the coins, but since there could be many different combinations, there is a second clue, which specifies how many coins the student has to use. Fun! There are two sets of cards: one is in easy-peasy to print black & white, the other is in cutesy colors (pink and light blue.) You can print out the cards, cut and laminate them and have them for the rest of

And we're back! This is the first of a set of "coin card" activities that I designed for our first grade teachers and which received universal "thumbs up, Robert!" from the students who used them. I even tried it out on a 2nd grader who needed some remediation and she went to town on it as well. So what's so good about these? Let me count the ways: 1) Quantity: there are 30 different cards, which means that its not so many that your kids will get lost, but not so few that they'll finish them
