Lesson Description - Estimating Sums and Differences of Decimals:
This lesson covers the idea of estimating sums and differences of decimals. Students learn to estimate the sum or difference of two decimals by first rounding each decimal to the nearest whole number, then adding or subtracting. For example, to estimate the sum of 4.94 and 2.185, round 4.94 up to 5, and round 2.185 down to 2, to get 5 + 2, which equals 7.
