Title
Borrow a friendly number, then put it back
Written script
Let’s make something useful. Would moving to a nearby round number make this job easier? Today: Use exact compensation and distinguish it from estimation. Here is our made-up source. An invented sticker design has 398 blue stickers and 267 plain stickers. Find the exact total. What do the numbers count? You can show, draw, type, sign or tell an agreeing helper. We will try one way together, then you choose a task. For fictional prompt cards, 497 + 186 = 500 + 186 − 3 = 683. Contrast the wrong 686: it counts the three extra cards. Invite a different check: 497 + 180 + 6. Your turn can be one useful part: Work 299 + 146 exactly using a friendly number, and name the adjustment. Keep, change, pause or finish. You do not have to read aloud, handle objects or hurry.
