Middle School Interim Assessment • IA 1 Book 1 Camden Prep Mt Ephraim
Annotated Step-by-Step Solutions: Model + US Algorithm & Multiplication Area Model: Tens: 60 + 20 = 80; Ones: 8 + 7 = 15; 80 + 15 = 95.
US Algorithm: 8 + 7 = 15 (write 5, carry 1); 1 + 6 + 2 = 9 ➔ 95 .
Both methods demonstrate regrouping 1 ten from 15 ones.
Area Model: 500 + 110 + 13 = 623.
US Algorithm: 8+5=13 (carry 1); 1+4+7=12 (carry 1); 1+3+2=6 ➔ 623 .
Place-value sums match vertical carrying steps.
Area Model: Regroup 83 into 70 + 13; 70 − 40 = 30; 13 − 7 = 6; 30 + 6 = 36.
US Algorithm: Borrow 1 ten: 13 − 7 = 6; 7 − 4 = 3 ➔ 36 .
Area decomposition directly explains why borrowing changes 8 to 7.
Area Model: 500 − 300 = 200; 110 − 70 = 40; 14 − 9 = 5; 200 + 40 + 5 = 245.
US Algorithm: 14 − 9 = 5; 11 − 7 = 4; 5 − 3 = 2 ➔ 245 .
Chained borrowing across tens and hundreds.
Total Product = 240 + 48 = 288
2×1 area model: 6 × (40 + 8) = 240 + 48.
Section 1: 7 × 200 = 1,400
Section 2: 7 × 50 = 350 ; Section 3: 7 × 4 = 28
Total = 1,400 + 350 + 28 = 1,778
3×1 area model decomposition.
Top-left: 30 × 20 = 600 ; Top-right: 4 × 20 = 80
Bottom-left: 30 × 6 = 180 ; Bottom-right: 4 × 6 = 24
Total = 600 + 80 + 180 + 24 = 884
2×2 area model: 4 partial products summed.
Top: 50 + 8; Left: 40 + 2
Quadrants: 2,000, 320, 100, 16
Total = 2,000 + 320 + 100 + 16 = 2,436
