Adding & Subtracting within 100 using Dienes – Year 2

Year 2 – Number – addition and subtraction
Solve problems with addition and subtraction using concrete objects and pictorial representations, including those involving numbers, quantities and measures.

Dienes that pupils can manipulate with their hands are common in most elementary classrooms with the rods for 10s & squares for units etc. These worksheets are an important transition away from the physical towards purely numerical calculations. 

Worksheets & Digital Teaching Resources

Addition
Both the worksheets & teaching resources are set at two levels:

1. The sum of the units are always below 10

2. The solutions require regrouping of 10 ones as 1 ten.

Subtraction

Both the worksheets & teaching resources are again set at two levels.

1. No borrowing is required, the minuend is always larger than the subtrahend.

2. The minuend is always smaller than the subtrahend, so the solution requires borrowing from the 10s to the units
