Test solutions with the detailed point scale. Add up your points and spot what to review.
1 Choose the word / 4 pts
- longer (1 pt)
- shorter (1 pt)
- tallest, because 14 is the greatest number (1 pt)

2 Three ribbons / 4 pts
- The blue ribbon, 7 cubes (1 pt)
- The red ribbon, 4 cubes (1 pt)
- Red 4, green 5, blue 7: red, green, blue (2 pts)
3 The helpful yarn / 3 pts
- The door is longer than the yarn, and the yarn matches the window, so the door is longer. (1 pt)
- The mirror is shorter than the yarn, so it is shorter than the window. (1 pt)
- mirror, window, door (1 pt)
4 Measure the marker / 3 pts
- Count the cubes: the marker is 9 cubes long. (1 pt)
- With gaps, the cubes do not cover the whole length, so she counted too few cubes. She must lay them end to end. (1 pt)
- \(12 - 9 = 3\). The pen is 3 cubes longer. (1 pt)
5 Snakes / 3 pts
- 11 is the greatest, so Mia’s snake is the longest. (1 pt)
- 6 is the least, so Ava’s snake is the shortest. (1 pt)
- \(11 - 8 = 3\). Mia’s snake is 3 blocks longer. (1 pt)
6 Hand spans / 3 pts
- Yes, both can be right. (1 pt) Their hands are not the same size, so the units are different. Dan’s hand is bigger, so he needs fewer spans than Ella. (2 pts)
