# Counting to 20: Get 'Em in Order!

October 11, 2015

Your students will have fun working with numbers to 20 with this exciting and interactive lesson with music, movement, and hands-on experiences!

### Learning Objectives

Students will be able to count, order, and say what number comes before and after a number from 0-20.

## Lesson

### Introduction (20 minutes)

• Explain to the students that they will be working with ordering numbers from 0-20 today.
• Play the Count to 20! video.
• Write the word “order” on the board, and explain that order is the arrangement of things in a particular pattern or sequence. You could order some students by their height as an example.
• Ask the students to come together and show them the 0-20 Number Line Template. Tell them that they will soon make their own.
• Show students how to cut out and glue the number line together.
• Display the numbers 1-20 in order and have the whole class count to 20 with you.
• Ask the students go back to their desks.
• Hand out the Number Line Template, and tell them to begin cutting and gluing.
• Go around and assist any struggling students with this task.
• When the students are finished, bring them back together to explain the next activity.

### Explicit Instruction/Teacher Modeling (5 minutes)

• Show students a bag of number cards and demonstrate pulling one out.
• Look at the number and say it.
• Hold up the number to the number line you previously made, and locate where it goes on the number line.
• Use adhesive putty to stick it to the board.
• Pull out another number and repeat the process.

### Guided Practice/Interactive Modeling (5 minutes)

• Continue this activity, and ask students to come up, pick a number, and show you where it goes in order compared to the other numbers already chosen.
• Ask students to explain their thinking when ordering the numbers.
• Tell the students that they will all get to order numbers at their desks.

### Independent Working Time (10 minutes)

• Ask the students to go back to their desks, and hand out the bags of Number Cards to them.
• Tell the students to pull out the numbers and put them in order.
• Remind them that they can use the number lines they made to help them if needed.
• Walk around and observe how the students order their numbers.
• When finished, ask the students to put their numbers back in their bags.

## Extend

### Differentiation

• Enrichment: To challenge students, put students in pairs. Tell the students to put their numbers in order from 1-20. Have one of the students look away while the other flips a card or two over. The other student looks at the numbers and says what card if flipped. Then switch and repeat.
• Support: Students can work with numbers to 10 before going on to 20.

## Review

### Assessment (5 minutes)

• Observe how the students ordered the numbers 1-20.
• Observe how they worked when comparing their numbers.

### Review and Closing (10 minutes)

• Bring the students back together.
• Select 20 students and give them numbers between 1 and 20.
• Ask the group to get in order from 1-20.
• Play the Count to 20! video again, and have the students sing and move.
