Activities

1. Start by practicing adding two-digit numbers together. Write down a few problems and solve them together.

2. Move on to adding three-digit numbers. Write down a couple of problems and solve them step by step.

3. Create a fun game where you give the student a set of numbers to add together. Time them to see how fast they can solve the problems.

Third Grade Talking Points

• "Adding numbers together is like combining groups of things. For example, if you have 3 apples and you add 4 more, how many do you have in total?"
• "When we add two-digit numbers, we start by adding the ones place first, and then the tens place. It's like stacking the numbers on top of each other."
• "When adding three-digit numbers, we use the same process, but we add the ones, tens, and hundreds place one by one."
