Lesson Video: 2-digit Addition With Regrouping

Skills Practice:

Written Practice:

Complete pages 30-31 in your workbook or download and print those pages.

Enrichment Activities:

Base-Ten Blocks & Mats. Download and print these in the lesson materials. You’ll need two copies of the first page so your child will have enough blocks. You’ll just need one copy of the mat, with the colored place value blocks. These are particularly helpful for solving multi-digit addition and subtraction problems with regrouping. This is a tough math concept with several steps, so having a visual to make the concept concrete, rather than abstract, benefits learners greatly. Your child will use this tool with many of his games this year, so keep it in a safe place!

Let’s Go SUM Fishing. Use this 2-digit addition game with regrouping to practice your new skills! Download and print the game in the lesson files. You’ll need counters, one color per player, to cover the fish. Coins, poker chips, legumes or any type of counter will work. Cut out the cards and stack them upside-down in front of the player(s). For a solo player, flip a card, figure out the answer to the addition problem using the base-ten blocks and mat, then cover the fish with that number on the game board.

Kids can play solo, against a timer, or you can make it a 2-player game by having the players compete to solve the addition problem and cover the fish with the correct sum. The player with the most counters on the board at the end of the game wins.
