5-A-Day Math Assessment: Week 1 - A comprehensive worksheet with 12 math problems for 5th-grade students, including expressions, area models, decimals, and graphing.

1. (6 × 9) - 8 = 54 - 8 = 46
2. 0.3 × 0.5 = 0.15 (Model: Shade 3 rows and 5 columns in a 10x10 grid, the overlapping area represents 15/100)
3. 1/4 = 0.25, 1/2 = 0.5; 0.25 + 0.5 = 0.75 (or 3/4)
4. 32,580 → 8 is in the hundreds place (value = 800); 1.687 → 8 is in the hundredths place (value = 0.08)
5. Word Form: Three thousand, six hundred fifty-nine; Expanded Form: 3000 + 600 + 50 + 9
6. 3.1 ÷ 1.58 ≈ 1.96 (using long division or estimation)
7. A: (7, 8), B: (9, 6), C: (4, 2), D: (10, 1)
8. 0.16 < 0.7
9. 3 × 1/2 = 3/2 = 1.5 (Model: Draw 3 circles, shade half of each)
10. 0.36 - 0.19 = 0.17
11. 0.1 ÷ 0.4 = 0.25 (Model: Use a 10x10 grid, show 1 row shaded for 0.1, divide into 4 equal parts to find how many 0.4 parts fit into 0.1)
12. 1/4 × 1/2 = 1/8 (Model: Draw a rectangle, divide into 4 equal vertical parts, shade one; then divide that shaded part into 2 equal horizontal parts, shade one of those)
