Counting the eggs

IMG_1595 (1)

“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?

What questions can you ask?

Next they used the Numicon shapes to help them count.

What’s the same and what is different?

Posted in Counting, Number sense, Subitising


Subitising is being able to look at a small set of objects (up to 5) and say how many there are without counting in ones. Once children can count objects reliably we want them to move onto subitising – an important step in the development of number sense.

Perceptual subitising – instantly recognising a small group of objects.

How many Digit Dogs can you see?

Conceptual subitising – seeing smaller groups within a larger group to say how many there are without counting in ones.


I know there are 7 because I see 5 and 2 more.

I know there are 7 because I can see 4 and 3 more.

Easter counting competition

Give each child an empty plastic Easter egg and ask them to fill it with as many objects as they can.

fill the egg




Fill the egg Cy

Count the objects to see who has the most. Organise the objects so that children can see how many there are without counting in ones. Put the objects onto the Numicon ten-shape, organise the objects so that they look like the Numicon shapes (see below) or put them on a ten frame.

Who won the competition? Who had more objects? Who had fewer objects?

What is the largest number of objects that you could fit in the egg?

What do you notice?

Encourage children to be good question posers. Posing questions develops mathematical thinking and reasoning skills.

Fill a container with mini-eggs and ask “What do you notice?”

Which of the things that you notice are mathematical?

Follow this by asking “What do you wonder?”

How many ways can you finish the sentence “I wonder……………..”

How many questions can you ask about the pot of eggs? Sort your questions – those that are mathematical and those that are not.

Can you ask good mathematical questions that can be explored, investigated and answered by your friends?

Put the questions on your working wall, use them in your maths challenge area, and as investigations in enhanced provision.

Easter Race to 10

Digit Dog and Calculating Cat have decided to play Race to 10 with their mini Easter eggs.


Who has fewer eggs? How many fewer?

How many more eggs does Digit Dog need to win? Can you answer in a full sentence?

Digit Dog has ……..eggs already and needs ……. more to make 10.

What about Calculating Cat?

Race to 10

A game for any number of players.

You will need:

  • A Numicon 10 shape each
  • A 1 – 3 dice
  • Numicon pegs for each player


Take turns to throw the dice. Count the number of pegs and put them on the 10 shape. First to get to 10 wins.

How many pegs does Digit Dog have?

How many pegs does Calculating Cat have?

Who has fewer pegs? How many fewer?

Who has more pegs? How many more?

How many more pegs does Digit Dog need to make 10? What about Calculating Cat?
