Counting to 20: Get 'Em in Order!

Explicit instruction/Teacher modeling

• 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

• 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

• 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.

• 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.

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

• 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.
