Find the missing part
Written script
Let’s make something useful. What needs to join a collection to reach the target? Today: Use addition/subtraction relationships for an unknown addend. Here is our made-up source. An invented card kit needs 725 cards in total. It already has 468. How many more are needed? 468 + □ = 725. 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. A fictional badge target is 630 with 275 available. Guide 275+□=630; 275→300(+25)→630(+330)=355. Check 275+355. Your turn can be one useful part: Solve 386 + □ = 540, and show the check in the original equation. Keep, change, pause or finish. You do not have to read aloud, handle objects or hurry.
