Relevance

Discuss with the students that it is important to be able to count amounts of money up to and including 100 dollars because you need this to calculate with money. If you can count money, for example, you know if you have enough money to buy something.

Introduction

There are starting numbers on the interactive whiteboard. Have the students continue counting in groups. In turn, they call a number and when the time has passed, ask the students to which number their groups have come.

Development

You show the coins and banknotes on the interactive whiteboard and read them out loud. Have the students repeat which coin or note it is. Then you explain that when you add notes and coins together, you first add the notes together and then you add the coins. Show a number of notes and coins on the interactive whiteboard and ask the students how you can conveniently add this amount up. They then add up the notes and coins. Indicate that you start with the notes. Then you add up the coins from the largest to smallest value. Explain that five 1 dollar bills have the same value as one 5 dollar bill. Show coins and bills in the correct order and let the students indicate the amount of money. They can choose from four answer options. The students then practice counting the amounts, with no answer options. Ask how the students can count this handy.

To check whether students can count whole amounts up to and including 100 dollars, you can ask the following question:
- How do you conveniently add up notes and coins?

Guided practice

The students practice counting the amount up to and including 100 dollars with answer options and without answer options.

Closing

You discuss again with the students that it is important to be able to count whole amounts of money up to and including 100 dollars because you need this to calculate with money. Check if the students know the correct order to add notes and coins. Then you show an amount on the interactive whiteboard. The students must indicate how much there is.

Teaching tips

Students who have trouble counting amounts up to and including 100 dollars can put the notes and coins in the correct order and then add them together. Emphasize that four quarter dollar coins are the same as 1 dollar.
