1 Quick problems / 4 pts

1. \(46 + 27 = 73\) monkeys. (1 pt)
2. \(82 - 35 = 47\) fish. (1 pt)
3. \(61 - 29 = 32\), so \(\square = 32\). (1 pt)
4. \(44 + 18 = 62\), so \(\square = 62\). (1 pt)

2 Crayons / 3 pts

(a) One bracket marked 58, with a box 24 and a box with a question mark. (1 pt)

(b) \(24 + \square = 58\) or \(58 - 24 = \square\). (1 pt)

(c) \(58 - 24 = 34\). There are 34 new crayons. (1 pt)

3 Jumping contest / 4 pts

(a) Compare: \(63 - 48 = 15\). Yara jumped 15 more times. (2 pts)

(b) Wes jumped fewer: \(48 - 9 = 39\). Wes jumped 39 times. (2 pts)

4 Hat shop / 4 pts

Step 1: hats sold: \(23 + 31 = 54\). (1 pt)

Step 2: \(75 - 54 = 21\). (1 pt)

Equation: \(75 - 23 - 31 = n\), so \(n = 21\). (1 pt)

The shop has 21 hats left. (1 pt)

5 Choose the operation / 3 pts

1. Add, because the group gets bigger. (1 pt)
2. Subtract, because we look for the missing part: \(60 - 24\). (1 pt)
3. Subtract, because we compare two amounts: \(52 - 35\). (1 pt)

6 Find the mistake / 2 pts

No, Eli is not right. He subtracted the ones the wrong way (7 − 2 instead of 12 − 7). (1 pt)

\(52 - 17 = 35\), so Eli has 35 stickers left. Check: \(35 + 17 = 52\). (1 pt)
