Answer:
fraction strips would just be;
1 box split into 12 parts because 12 is the common denominator, and 1/4 is equal to 3/12, so you would shade in 3 of the parts, and then 1/6 = 2/12, so you would shade in 2 parts. In the end, you should have a box (or rectangle) with 12 parts, and only 5 of those parts should be shaded in.
The equation would be as follows:
1/4+1/6 = 3/12+2/12 = 5/12
Hope this helped!! :)
