Description: This deck of digital task cards is a fun way to help students practice adding 3 numbers together! The first two cards show completed ten frames with audio directions. The audio directions remind students to look for numbers that make a 10, doubles, or two numbers they know the sum of before adding on the 3rd number. The remaining cards (3-30) have interactive ten frames where students can drag colorful dots to help them find the sum of the three numbers. They do not need to use the ten frames in order to get the question correct. Boom Cards™ are perfect for centers, morning work, as an alternative to a worksheet, or online with distance learning! Students LOVE getting instant feedback on their answers. This deck has a total of 30 cards and is set to show 15 cards at a time in random order. Each card includes audio directions.

To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
