🔢 Part 1: Tiered Vertical Addition

Write each calculation using the vertical method. Show your working in the boxes. After each answer, use a quick estimate to check if your answer is reasonable.

Success criteria: I can line up digits by place value, carry correctly when needed, and check my answer by estimating.

Differentiation strategies: Choose a level that suits you. Use a place-value chart or counters if you need concrete support. Pair up with a classmate to explain your steps.

Extension for advanced learners: Create a related word problem that needs vertical addition and solve it (see Part 2).

1. Level 1 — No regrouping: 246 + 153 =

2. Level 1 — No regrouping: 482 + 307 =

3. Level 2 — Regrouping: 376 + 589 =

4. Level 2 — Regrouping: 1,247 + 865 =

5. Level 2 — Regrouping: 2,995 + 1,208 =

6. Level 3 — Challenge: 4,678 + 3,795 =

✏️ Part 2: Reasoning, Check & Extension

7. Estimation check: Estimate 1,247 + 865 by rounding to the nearest hundred. Is your calculated answer reasonable?

Yes

Explain your estimate (quick working):

8. Create & solve: Write a short two-step word problem that uses vertical addition (use three- or four-digit numbers). Then solve it using the vertical method.

9. Reflection: Which success criterion did you find easiest? Which did you need help with?

Extension activities: Add three numbers (e.g. 1,248 + 967 + 432) using vertical addition and explain how you carried digits. Try converting a word problem involving dollars ($) or kilometres (km) into a vertical addition calculation.

Teacher note: Encourage students to use inverse subtraction to check answers and to discuss strategies with a partner for formative assessment.
