Snap Cubes make natural and appealing counters. Since they snap together firmly, they are useful for young students as number models. If students build a stick (a group of cubes connected end to end) corresponding to each number from 1 to 10, it is natural for students to arrange them in a staircase and to talk about greater and less, longer and shorter. Numbers might also be represented by the following cube patterns, which are easily sorted into "even" ones, in which each cube is paired with another, and "odd" ones, in which there is an "odd man out."
Snap Cubes also help students to more easily see relationships such as the following:
Since there are large numbers of cubes in a set of Snap Cubes, they are useful for estimating and for developing number sense. Students can make a long stick with the cubes, estimate how many there are in the stick, and then separate it into sticks of 10, identify how many tens they have, and count the leftovers to find how many ones there are.
The colors of the cubes further make them useful in developing the concept of place value. Each color can represent a place value, and students can play exchange games in which, if they have 10 of one color, they can exchange them for one of the next color.
Snap Cubes are very suitable for developing an understanding of addition. They can be used as loose counters, with a different color for each addend. The colors can also broaden students’ understanding of subtraction. Students often think initially of subtraction as "take away." To act out 6 – 4, students put out 6 cubes and take away 4.
Snap Cubes are also ideal for developing the concept of multiplication, both as grouping and as an array. To show 3 × 4, students can make 3-inch sticks with 4 in each and count them all. Arranging these cubes in a rectangular array not only makes it visually easy to understand why 3 × 4 = 4 × 3 but also leads naturally into a model for understanding the formula for the area of a rectangle. In addition, Snap Cubes are suitable for exploring area, perimeter, volume, and surface area relations.
Snap Cubes are a wonderful tool to use in helping students to represent numbers in terms of factors and to understand procedures for finding greatest common divisors and least common multiples. Snap Cubes are also a natural unit for measuring length, and using them can lead to early experience of ratio and proportion. Students can measure the same length in Snap Cubes and in another unit, perhaps inches. They can record their results for a few different lengths. They may then measure in just one unit and predict the measure in the other.
