01

What Students Need to Do

Students decide which operation fits a context, break numbers into useful parts, and show how the parts combine. They compute accurately with large whole numbers and explain whether the answer makes sense.

02

What Mastery Looks Like

Given an unfamiliar problem, a student writes a matching equation, uses partial sums, differences, products, or quotients, and labels the answer. The student checks with estimation or an inverse operation and explains each step.

03

Common Misconceptions

Students may add every number shown or rely on clue words instead of identifying the unknown. They may misalign place values, regroup incorrectly across zeros, or omit partial products. In division, they may discard a remainder when the context requires rounding up or naming what is left.

04

How to Assess It

Exit ticket: “A warehouse has 128,450 notebooks and ships 275 cartons of 36 notebooks each. How many notebooks remain?” Require an equation, labeled work, and an estimate.

1. 01

   Use place-value disks and a labeled mat to model 63,402 minus 27,856, regrouping units before recording the written steps.

2. 02

   Post two solutions for 2,304 divided by 16; students identify the clearer part-whole strategy and defend their choice in writing.

3. 03

   Play Equation Match: teams pair context cards with equations, solve them, and earn a point only after an estimation check.

4. 04

   Give students a school supply invoice with quantities and unit prices, then ask them to find the total cost and remaining budget.
