We worked on putting things in order from longest to shortest/shortest to longest. Today we are going to practice that again, but we are going to do it after measuring three lengths.
We measure all the time in real life. When your mom sees if you have a fever, she is measuring how hot or cold you are. When you check the clock, you are measuring how many minutes something takes. Fishermen have to measure fish to determine if they are a keeper or not. When we measure how long something is, we are measuring length.
Your thinking job today is: When we put lengths in order, what pattern do we notice in the numbers?
Present problem: I have 3 shoes that I need to measure and then put in my shoe store. I organized my shoes from shortest to longest. How can I put these in order?
I will have 3 students take off their shoes (giggling begins!) to use in the shoe store.
I’ll choose 3 students to model measuring the shoes with cubes, and then have a student put the shoes in order from shortest to longest.
Guiding Questions (after ordering the shoes from shortest to longest):
"Now you are going to get your own set of 3 shoes. I want you to measure them and order them from shortest to longest." (See attached Student Share documents!)
As students work, I’ll check to make sure:
Bring students back together. I’ll have one student share out their measurements and how they ordered them.
Intervention (Group A): Students measure and order 3 shoes. Students have the scaffold of which one goes first in the boxes to help them remember how to order from shortest to longest/longest to shortest.
Extension (Group C): Students draw a fourth shoe. They have to determine if the 4th shoe should be bigger or smaller (depending on if they are ordering from shortest to longest or longest to shortest)
See attached independent practice documents!
Students share their measurements and how they ordered with a partner. Partner checks the work to make sure it is ordered correctly.
