Place Value


Over the last week, we have been learning about place value in maths. Place value tells you what the different digits in a number are worth. We are still getting the hang of it but we've been practicing using some great games. We played "Race to 50" and "Race to 100" to help us learn about groups of 10 and ones. To play them you roll a die (6 sided) and cover up each number as you roll. The first person to the end is the winner! We used counters to play race to 50 and MAB or buttons to play race to 100. 

Here is what we've learnt:

Place value is the hundreds column, tens column and the ones column. Ilya

Today we played a game called race to 100! Gareth

Place value is about columns and how much the numbers in each column are worth. Romola

For example, in the number 345 the 3 is worth three hundred. Lucy

For example, in the number 74 the 4 is worth 4. Mia

For example, in the number 691 the 9 is worth 90, it is 9 groups of 10. Clarrie

I learnt that 294 and 29 are different because one of them has a hundreds column. Felix
