Big, bigger, biggest!
Comparing size is one of the first math skills kids learn. Preschoolers and kindergartners use words like big and small, tall and short, long and short and line things up side by side. First graders order three objects by length and learn to compare two things using a third, like a string. By second grade they measure with rulers in inches and centimeters and find how much longer one object is: 9 in − 6 in = 3 in. The click moment is when kids learn to line up the ends before deciding which is longer.
Size starts with real stuff kids can hold. These moves build the vocabulary and the habits of good measuring.
Grab three stuffed animals, three shoes or three pencils and have kids line them up from smallest to biggest. Then use the words: big, bigger, biggest. Once they can do it with objects, they're ready to do it on paper.
Why it works: the U.S. Department of Education's guide for teaching elementary math recommends moving from hands-on objects to drawings to numbers.
Try it withBig Bigger Biggest WorksheetWorksheetsOpen it →Hold two pencils up at uneven ends and ask "Which is longer?" Kids will disagree. Have partners explain how they know and discover that the ends have to line up. That one conversation makes comparing lengths fair from then on.
Why it works: when kids say the precise math words, their understanding gets sharper, a recommendation of the U.S. Department of Education's elementary math guide.

Why it works: showing first, practicing together, then letting kids try alone is the "gradual release" model teachers have relied on for decades (Pearson and Gallagher, 1983).

Most children start comparing sizes around age 3 or 4 with words like big and small. In kindergarten they compare lengths and heights directly, and in 1st grade they order three objects.
Use three real objects of different sizes. Show "big," then add a bigger one and the biggest one. Let your child arrange them and name each.
Often the ends aren't lined up. Show them to put both objects on the same starting line before comparing.
