This addition with regrouping math enrichment resource came to me as I continue to search for low prep, ready-to-print ways to challenge my top math students and provide enrichment while still addressing all rigorous state standards. These tasks incorporate higher level thinking, estimation strategies, and have multiple solutions! I want students to be able to work independently or with peers so directions need to be simple and easy to follow. My 3 digit version has always been a best seller, so I knew a 2 digit edition would be so helpful!

In addition to providing a HUGE amount of practice on addition with regrouping and problem solving, this resource is designed to really help students develop their understanding of place value and number sense—critical foundations for more advanced math concepts. Students are asked to do a number of different activities requiring estimating and addition with regrouping. There is a TON of flexibility with this resource, and I hope you can find a great way to make it work for you and your students! I designed it to be very low ink as well.

So—what are your options? For me, I love having the Mind Boggling Math displayed in my room so students can access it any time. If you don’t have the wall space or want to use it with only one child, don’t worry! I have included a single page version of the board and really everything you need is included on the student sheets! It can be a stand alone resource! So what do you get?

--Letters to spell “Mind Boggling Math” for a bulletin board (optional)

--Full page number grid for non-displayed use

--The numbers ready to cut out and use on a display

--6 quality problem solving activities to challenge your intermediate students

--5 ADDITIONAL “Even More” challenges so you can use this activity over and over again!

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.
Fluently add and subtract multi-digit whole numbers using the standard algorithm.
Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction.
Add and subtract within 1000, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method. Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds.
Add up to four two-digit numbers using strategies based on place value and properties of operations.
