Charlotte has a box of shapes to sort and count. How many groups has she put the shapes into? How many hexagons did she find? How many shapes were in the box altogether?
Let’s count how many groups she put the shapes into: one, two, three, four, five. Now let’s count how many hexagons she found: one, two, three, four. How many shapes were in the box altogether? There are six circles and one star, three triangles and four hexagons, and two squares.
Six and one makes seven. Seven and three makes 10. 10 plus four makes 14. 14 plus two makes 16. Charlotte sorted the shapes into five groups. She found four hexagons, and there were 16 shapes in the box altogether.
