Content for senior infant class

The child should be enabled to

• Develop an understanding of the concept of capacity through exploration and the use of appropriate vocabulary?
• Compare and order containers according to capacity?

Fill one container and pour contents into another.
Compare the capacity of two very different containers, noting that both can hold the same amount.
Compare three containers; arrange in order of capacity; label, e.g. holds more/holds most
.

• Estimate and measure capacity in non-standard units?
Present simple problems such as, estimate (guess) how many spoons or egg-cups of sand or dried peas will fill the cup or how many jugs of water will fill the bucket?
Use the same unit to fill two different containers & check by measuring.
Record results using one counter for each cup or jug poured as children work in pairs.
• Select and use appropriate non-standard units to measure capacity.
Present simple problems such as how can we find the capacity of the bucket?
Which unit will we use (teaspoons or cups)? Discuss reasons for choice.
