Grade 4 · Common Core State Standards: 4.NBT.B.6

Question 1 – Mental math [2 pts]

  1. 36 tens ÷ 6 = 6 tens. 60
  2. 40 hundreds ÷ 5 = 8 hundreds. 800

Scoring: 1 point for each answer.

Question 2 – Two-digit dividends [2 pts]

  1. \(80 \div 4 = 20\) and \(16 \div 4 = 4\). 24
  2. \(6 \times 14 = 84\) and \(87 – 84 = 3\). 14 R 3

Scoring: 1 point for each answer.

Question 3 – Three-digit dividend [2 pts]

\(500 \div 5 = 100\); \(125 \div 5 = 25\). Quotient \(100 + 25 = 125\).

Check: \(125 \times 5 = 625\).

125

Scoring: 1 point for 125. 1 point for the check.

Question 4 – Remainder in the tens place [2 pts]

1008770056
700 + 56 = 756, with 2 left.

\(758 – 700 = 58\); \(7 \times 8 = 56\); \(58 – 56 = 2\).

Check: \(108 \times 7 + 2 = 758\).

108 R 2

Scoring: 1 point for 108. 1 point for the remainder 2.

Question 5 – Four-digit dividend [2 pts]

\(6 \times 800 = 4{,}800\); \(4{,}872 – 4{,}800 = 72\); \(72 \div 6 = 12\).

\(800 + 12 = 812\)

Check: \(812 \times 6 = 4{,}872\).

\(812\)

Scoring: 1 point for correct partial quotients. 1 point for 812.

Question 6 – Read the area model [2 pts]

20040751,00020035
200 + 40 + 7 = 247.

\(1{,}000 \div 5 = 200\), \(200 \div 5 = 40\), \(35 \div 5 = 7\).

\(200 + 40 + 7 = 247\)

247

Scoring: 1 point for the three widths. 1 point for 247.

Question 7 – School vans [3 pts]

  1. \(83 \div 6 = 13 \text{ R } 5\) because \(13 \times 6 = 78\) and \(83 – 78 = 5\). 13 vans
  2. 5 students
  3. The 5 students need one more van. 14 vans

Scoring: 1 point for each part.

Question 8 – Find the mistake [3 pts]

  1. \(14 \times 5 + 3 = 70 + 3 = 73\), which is not 523.
  2. \(5 \times 100 = 500\); \(523 – 500 = 23\); \(5 \times 4 = 20\); \(23 – 20 = 3\). 104 R 3
  3. There are 0 tens left after taking 500, but Liam skipped the zero and wrote 14 instead of 104.

Scoring: 1 point for each part.

Question 9 – Photo album pages [2 pts]

\(7 \times 60 = 420\); \(458 – 420 = 38\); \(7 \times 5 = 35\); \(38 – 35 = 3\).

Check: \(65 \times 7 + 3 = 455 + 3 = 458\).

65 full pages; 3 photos left

Scoring: 1 point for 65. 1 point for 3 left.

Total

20 points
