This week in maths we have been thinking about place value.
Place value is the value of each digit in a number. It means understanding that 52 is made up of 50, and 2, rather than 5 and 2. That is a tricky concept so we used a variety of maths apparatus to help us .
You could play "Shark numbers" on our "useful websites" link on the Year 1 page to help understand the idea of tens and ones in numbers to 99.
