Maths

This week we are adding and subtracting ones, then tens, from a 2 digit number.

eg 24 + 5      47 - 4      23 + 30     45 - 20

 

Watch the videos, complete the worksheet and quiz.

Can you practice counting in tens from any 1 digit number? Write them down to help you. Count forwards and backwards - can you hear the pattern?

 

eg 4, 14, 24, 34, 44, 54, 64, 74, 84, 94

 

eg 7, 17, 27, 37, 47, 57, 67, 77, 87, 97

Use the 100 square to help you. Start with a 1 digit number ad follow the coloured stripes down.
