Easter Estimation

Digit Dog and Calculating Cat have been inspired by Steve Wyborney www.stevewyborney.com to create this estimation activity.

Show the first slide and ask:

How many eggs are in the pot?

Take estimations and then reveal the answer.

Show picture 2 and ask the same question. Compare the pots – are there more eggs or fewer eggs? Take some estimates and then reveal the answer.

Show picture 3 but this time ask learners to write down their estimation and then to tell their partner why they chose that number. This generates mathematical talk and explanations.

I chose _____ because___________

I looked at pot __ and thought__________

I think __________ because_____________

Repeat for picture 4.

Easter estimating

Digit Dog and Calculating Cat are estimating how many eggs are in the pot.

“I wonder how many eggs are in the pot?”

Can you estimate?

What do you think?

Will there be more than 10? How many more? A lot more? A few more?

Will there be more than a 100?

Digit Dog and Calculating Cat used the egg boxes to help find out how many eggs there are. They wanted to organise the eggs so that they could see how many there are without counting in ones.

What do you notice?

How do the egg boxes help to see how many eggs there are?

How can you count them?
