About this worksheet
Big and small describe how much space a whole object takes up. Long and short describe distance from one end to the other. Preschoolers mix the two, partly because a long thing often looks big, and partly because they are asked to judge one object on its own. No object is big by itself. It is big compared with something, which is why every question here shows three things at once: three shapes drawn at three sizes, or three rows of same-size pictures drawn at three lengths. Ready sheets ask for the biggest and the longest, the ends children notice first. Practice sheets ask for the smallest and the shortest, which is the same comparison run the other way and is genuinely harder. Stretch sheets ask for the one in the middle, which cannot be answered by finding an extreme at all: the child has to put all three in order. Ask for a full sentence, because the comparison lives in the sentence: this one is the longest of the three.
What your child will learn
Compare three objects and find the biggest
Find the smallest and the shortest, not just the biggest
Put three lengths in order to find the middle one
Use size words as comparisons rather than labels
Worked example
Three rows of pictures sit side by side. Two rows keep going and one row stops early, so the row that stops early is the shortest.
Common mistake
Calling one object big without comparing it with the others on the page.
