How many objects can you fit in the egg?
Digit Dog and Calculating Cat are trying to fill their plastic eggs with as many objects as they can.
Try this out for yourself – each person needs an empty plastic Easter egg or any small container to fill with as many objects as they can. The one who collects most objects is the winner.
Count the objects to see who has the most. Organise your objects so that you can see how many there are without counting in ones.
Do this by:
- Organising the objects into tens. How many do you have? “I have one ten and eight”.
How many objects does Digit Dog have? Don’t count in ones.
Does he have more or fewer objects than Calculating Cat? Explain how you know.
2. Putting the objects on a 10-frame (download here).
Who collected the most objects? How do you know?
How many more objects does Calculating Cat need so that she has 20? How can you work it out by looking at the 10-frame?
3. Putting the objects in egg boxes.
Who was the winner? Who had more objects? Who had fewer objects? Can you quickly count the objects? Make a chart to show how many objects each person collected.
