Estimate the sum or difference calculator
Activity overview: - Texas Instruments
Call out the sum or difference of two fractions (proper or mixed), such as + and instruct students to estimate the value of the sum or difference using the benchmarks from exercise 1. For example, students should be encouraged to think of as 4 and as , giving a sum of . Have students mark and send this location like in Exercise 1.

The corrected sum of squares (CSS) is calculated as the sum of the squared distance from each treatment mean to the grand-mean. For example, there are two treatments with mean of 10 and 20, respectively. That gives us a grand mean of (10+20)/2=15 (assuming equal cell size). Therefore, the corrected sum of squares is: (10-15)2+(20-15)2=50.
