Learning focus: Beginning-of-year review of rounding, estimation and adding whole numbers.
Panel 1 — Checking Their Distance
Caption: Nova skated 368 metres. Jax skated 427 metres.Nova: “About how far did we skate altogether?”Jax: “Let’s estimate before calculating the exact answer.”
Panel 2 — Making an Estimate
Jax: “We can round 368 to 400 and 427 to 400.”368 ≈ 400
427 ≈ 400
400 + 400 = 800Nova: “So we skated approximately 800 metres altogether.”
Panel 3 — Finding the Exact Answer
Nova: “Now let’s add the exact distances.”368 + 427 = 795Jax: “Seven hundred ninety-five is close to our estimate of 800.”Nova: “That tells us our answer is reasonable!”
Panel 4 — The Funny Finish
Nova: “We skated 795 metres. That’s almost 800!”Jax: “My tired legs have already rounded it up to 8,000!”
