We could simply say, “To find the area you need to multiply the length times the height.” When we pull out manipulatives, we give our children the chance to understand the in and outs of a problem. The majority of the time I didn’t have a clue as to why I was doing what I was doing. ![]() #Perimeter and area worksheets free printable how to#My math education consisted of the teacher telling me how to solve a problem and then performing that operation over and over. Our upper elementary kiddos will follow the same steps as our younger children, but instead of doing basic operations with whole numbers, they will be forced to add and multiply mixed numbers. You will notice that the value for those rods is never mentioned, adding another level of difficulty to this problem.īut just so you know, the light green equals 1/2 and the red equals 1/3 of the dark green rod!!
