 # Kindergarten Math

## What do I need to know about my child's education?

We know that child development happens in steps that are developmental and sequential. Many skills are worked on throughout the year. By the end of kindergarten, we expect students to master the following math skills.

### Know basic number concepts

• Count to 100 by ones and by tens.
• Count forward from a given number instead of having to start at 1.
• Count the number of objects in a group, up to 20.
• Write numbers from 0 to 20 to tell how many objects are in a group.
• Tell if a group of objects has more, less or the same number as another group.
• Compare two numbers between 1 and 10 presented as written numerals.

### Add and subtract with single digit numbers

• Solve simple word problems involving adding and subtracting, like "Mary has 5 beach stones. She finds 4 more. How many beach stones does Mary have altogether?" Use objects or drawings. The total amount should be 10 or less.
• For any number from 1 to 9, find the number that makes 10 when added to the first number.
• Learn the addition and subtraction facts within 5 (that is, only combinations that add to 5 or less).

### Add and subtract some two-digit numbers

• For numbers 11-19, show with drawings or blocks how these numbers are made up of one group of 10 and some additional ones.

### Measurement and geometry

• Know what the words length and weight mean for a given object. Compare two objects to say which has more or less. For example, directly compare the heights of two children and describe one child as taller/shorter.
• Identify and describe shapes (squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders and spheres).
