1. \(36 + 27 = \mathbf{63}\) (\(6+7=13 \rightarrow\) 3 ones, carry 1 ten: \(1+3+2=6\))

2. \(45 + 38 = \mathbf{83}\) (\(5+8=13 \rightarrow\) 3 ones, carry 1 ten: \(1+4+3=8\))

3. \(59 + 24 = \mathbf{83}\) (\(9+4=13 \rightarrow\) 3 ones, carry 1 ten: \(1+5+2=8\))

Level 2 (Standard Equations)

4. \(67 + 25 = \mathbf{92}\)

5. \(48 + 48 = \mathbf{96}\) (Double facts!)

Level 3 (Challenge)

8. \(278 + 154 = \mathbf{432}\) (Regroup ones to tens and tens to hundreds)

9. Target 100: \(47 + \Box = 100 \rightarrow 100 - 47 = \mathbf{53}\).

Quick Fix: "Deal like a card dealer: one for you, one for you, one for you. When you finish, recount every circle to ensure they match!"

Differentiated Support Instructions

Tier 1: Needs Support

Provide scratch paper to draw large sorting plates. Have students cross off tallies from the total as they place dots into each plate.

Tier 2: On-Level

Complete Level 1 & Level 2 equations. Encourage using multiplication memory: "Ask yourself: what times the divisor equals the total?"

Tier 3: Early Finishers

Write out all 4 family facts for Level 3 (e.g. \(4 \times 5 = 20, 5 \times 4 = 20, 20 \div 4 = 5, 20 \div 5 = 4\)).
