Estimating sums and differences can be a lot of fun for kids! Here are some easy tips to help:

1. Rounding Numbers: Show students how to round numbers to the nearest ten. For example, if you want to estimate the sum of $32 + 47$, round $32$ down to $30$ and $47$ up to $50$. Then, you can add $30 + 50 = 80$.

2. Friendly Numbers: Use numbers that are simple to work with. For example, when figuring out $58 - 23$, think of $58$ as $60$ and $23$ as $20$. So, $60 - 20 = 40$. That’s pretty close to the real answer!

3. Visual Aids: Use number lines or blocks to show how rounding and estimation works.

By practicing these tricks, students can feel more confident using estimation in their daily lives!
