# New! Calculating in whole dollars up to \$10

Today, I’m excited to tell you about a new interactive resource Let’s go shopping.

The resource consists of five lessons which give children practice with counting, adding and subtracting up to 10 in a shopping context using whole dollars.

The lessons each have a different focus and are designed for teacher-led discussions with the whole class or a small group. The preparation is done for you. All you need to do is teach.

#### Shop 1 item

Children are shown a toy with a price in whole dollars up to \$10.

Children drag coins needed to pay for the item from the money bag onto the shopkeeper’s hand. When they think they have counted the correct number of coins to pay for the item, they click ‘pay’.

If they are incorrect, a sign ‘oops’ appears. They click on the sign to try again.

#### Give change for 1 item

In this scenario, children have a \$10 note to spend. They are shown a toy with a price in whole dollars up to \$10 and determine the change they would receive from \$10.

Children drag the coins needed for change from the shopkeeper’s hand onto the money bag.

They may work out the answer before counting, or they may begin counting with the cost of the toy and count how many more \$1coins to make \$10.

When they have counted the correct number of coins, they click ‘check’.

If they are incorrect, a sign ‘oops’ appears. They click on the sign to try again.

#### Shop 2 items

As for Shop 1 item, but this time children work out the cost of buying two items. They may add the cost of items first, or drag the coins needed for one item and then the other until they have the total.

#### Give change for 2 items

As for Give change for 1 item, but this time the children will need to work out the cost of both items before they can determine the change.

Each of these first four lessons consists of ten slides.

To extend the learning, you could consider having children work out the answer using coins or counters before completing the task on the screen. You might also get them to write the number sentence to match.
