Directions:
- Using the virtual place value chart and base ten blocks, practice adding the following problems.
- Draw models and equations in your notebook.
- 312 + 209 =
- 196 + 356 =
- 447 + 268 =
In Your Math Notebook:
Let’s get out our math journals and work through the following application problem. Make sure you read the problem carefully, draw a picture to match your thinking and write and solve an equation. Make sure to find an exact answer when there is not a clue that tells you to estimate.
Read, Draw, Write. DONE!
