This week in Year 3 Maths, we have been learning about the composition of 3-digit numbers. We explored why numbers are grouped into hundreds, tens and ones and how this helps us understand their value.
Using practical resources, the children investigated how a number is built, for example how 342 is made from 3 hundreds, 4 tens and 2 ones. We discussed how regrouping numbers in this way makes it easier to read, compare and work with larger numbers.
The children showed great curiosity and understanding as they explained their thinking and represented numbers in different ways. This strong foundation will support them as we move on to more complex maths work.
To support our learning, we used the MathsBot Base Ten Blocks website to build numbers and explore their composition. This allowed the children to clearly see how 3-digit numbers are made up of hundreds, tens and ones.
Help at Home:
Use MathsBot to build different 3-digit numbers with your child. Ask them to explain their thinking using this sentence frame:
“There are ___ hundreds, ___ tens and ___ ones.
The number is ___.”
This will help reinforce place value understanding and mathematical language at home.
