Key idea

model addition and subtraction within 1,000 and connect each trade to a written step.

Sample problems

Model 236+147. Write the sum and explain a trade.
Model 383−147. Show a trade for the ones.
Add 236+200 using a drawing.
Subtract 100 from 383. Show which place changes.

Common mistakes to watch for

Use a picture, objects or another calculation to check.

The answer key explains each one, so you can tell what a wrong answer means.

How to use this set

Teach with the slides (about 15 minutes): a warm-up, the big ideas, a “spot the slip” challenge, Mr DJ’s worked example, and a pick-your-pepper round on whiteboards. Or watch the video together.
Practice with the worksheet. Everyone does Mild and Medium, then climbs to Spicy and Extra Spicy.
Check understanding with the exit ticket, and send the homework home.
Mark with the answer key — each answer shows the steps and the most likely mistake. The slides’ teacher notes are in the key too.
