# Math Challenges - Algebraic Thinking "Bubbles" Problem Solving Task Cards

- PDF

### Description

**Understanding the concept of “equal” is a critical part of developing number sense and algebraic thinking. **This problem solving resource helps students get more flexible “playing” with numbers as they try to use algebra thinking to figure out what numbers can fit to make the problems true. It can really help solidify addition, subtraction, and estimation skills but in a super fun way!

Each task card has a set of bubbles that are connected to either 2 or 3 other bubbles. Students are given the total for each adjoining bubbles, and students need to use their reasoning and even “guess and check” to determine which numbers will work in the bubbles to make all the totals accurate.

Look at the preview for more explanation. Considering modeling with a few to help students see some of the strategies they can use as they tackle these great challenges!

Use as a math station…as a class review…with an intervention group—or throw individual cards under a document camera for a class warm up! I have included the cards in color and gray tones for complete flexibility. Recording sheets and answer key are included as well! Check the preview for even more ideas and suggestions. ENJOY!
