Title
Ten ones can travel together
Written script
Let’s make something useful. Make a plan for a collection that crosses a ten or a hundred. Today: Regroup an addition without changing its value. Here is our made-up source. An invented costume cupboard has 364 tags, then receives 278 tags of the same kind. Find the new count. 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 picture station joins 527 cards and 186 cards: 527 + 100 = 627, +80 = 707, +6 = 713. Ask the learner to show where a hundred boundary was crossed. Your turn can be one useful part: Try 258 + 167. Show the regroup or describe it exactly. Keep, change, pause or finish. You do not have to read aloud, handle objects or hurry.
