### Lesson plan

# Order Up!

#### Learning Objectives

Students will order objects by length.

The adjustment to the whole group lesson is a modification to differentiate for children who are English learners.

#### Introduction

*(5 minutes)*

- Use snap cubes to make three towers of different lengths. If possible, make each tower with a different colour cube.
- Show the towers to the class and ask, “Which tower is the longest?”

#### Explicit Instruction/Teacher modeling

*(10 minutes)*

- Now ask, “Which tower is the second longest?” and “Which tower is the shortest?” Model how to put the towers in order from shortest to longest.
- Count how many cubes are in each tower and write their lengths on the board.
- Call on a student to come to the front of the class and make a tower that is longer than all the other towers. Count the number of cubes in the tower and write the number on the board.

#### Guided practise

*(10 minutes)*

- Now hand out snap cubes to the class and challenge students to create a tower that is shorter than all the other towers.
- Have students count and share how many cubes are in their tower.
**Compare**The towers that the students made. Ask, "Do they all have the same numbers of cubes? Why or why not?"

#### Independent working time

*(15 minutes)*

- Tell students that they are now going to make three towers out of snap cubes. When they are done, students should switch towers with a partner. Each student should put their partner’s towers in
**Order**From smallest to largest, writing the lengths of each tower on their papers. - When partners are done with this activity, they should complete the Length worksheet.

#### Differentiation

**Support:**

- Have students make two towers to order.

**Enrichment:**

- Have students make four or more towers to order.

#### Assessment

*(5 minutes)*

Assess students’ understanding by observing how they ordered the snap cube towers and by assessing their worksheets.

#### Review and closing

*(5 minutes)*

Call on students to share the towers that they ordered with the class.
