This week in Maths, we have been learning how to add multiples of 10 to a 2-digit number. We used our class shop to help us solve real-life money problems, such as adding £20 to an item costing £23.
To support our understanding, we represented numbers using tens and ones and recorded them on a tens and ones chart. We noticed that when we add a multiple of 10, the tens digit changes while the ones digit stays the same.
Try this at home: Ask your child questions such as:
- 34 + 20 = ?
- 52 + 30 = ?
- 17 + 40 = ?
Encourage them to explain what happens to the tens and ones in each number.
