## Estimation With Decimals – Let’s Break it Down!

When teaching students about estimating with decimals, students can use a few different methods. One way is using their knowledge of rounding to make each number an easy whole number to work with. A second method is to use benchmark values. This type of estimation involves using whole numbers and those with 0.25, 0.5 and 0.75. When using benchmark values, the hope is that the estimated sum or difference will be closer to the actual answer.

## Year 6 Maths Questions – Coming Right Up!

If you are looking for some estimation questions to add to your year 6 maths lessons, you have come to the right place! Teach Starter has created a set of 24 task cards for your students to practise estimating sums and differences with decimals.

To complete these task cards, students will use rounding and benchmark values to solve standard practise problems as well as word problems. Additionally, this teacher-created resource comes with a recording sheet for students to write down their answers and an answer key for quick and easy grading!
