In previous lessons, students learned how to count up to 110 objects and connected written numbers to quantities.
In this lesson, students measure a length between 95 and 120 length units long and represent their count using numbers. Then, students create a poster to show a drawing of their count, without including the written number. When students participate in a gallery walk to view each poster, they record the numbers represented.
- Measure length and determine an efficient way to count the number of length units up to 120.
- Read and write numbers to 120.
- Let’s count, write, and read numbers up to 120.
- Put strips of tape on the floor, 2–3 of each length. Label with the animal name. There should be one length of tape for each group of 3.
- Beaver: 95 centimeters
- Snake: 105 centimeters
- Giant Anteater: 120 centimeters
- Dog: 110 centimeters
- Raccoon: 100 centimeters
- Red Fox: 115 centimeters
- Make bags or buckets of about 125 base-ten cubes per group of 3.
