Counting and Cardinality
- Counting to 100 by Ones and by Tens
Kindergarten counting: say the numbers to 100 by ones and by tens, count on from any number, and write the numbers from 0 to 20, with pictures and practice.
- How Many? Counting Objects One by One
Kindergarten counting: touch each object once, why the last number said tells how many, how each next number is one more, and counting things in rows and lines.
- More, Less and the Same
Kindergarten comparing: decide which group has more, fewer or the same number by matching or counting, and compare two numbers from 1 to 10.
Addition and Subtraction
- Adding and Taking Away Within 10
Kindergarten addition and subtraction: put groups together and take some away with objects and drawings, solve story problems within 10, and know the facts within 5.
- Making Ten and Breaking Numbers Apart
Kindergarten number sense: break numbers up to 10 into two parts in more than one way, and find the number that makes 10 with any number from 1 to 9.
Place Value
- Teen Numbers: Ten and Some More
Kindergarten place value: see the numbers 11 to 19 as ten ones and some more ones, with ten-frames, drawings and number sentences like 14 = 10 + 4.
Measurement & Data
- Comparing Objects: Longer, Taller, Heavier
Kindergarten measurement: describe what can be measured about an object, like length, height and weight, and compare two objects to see which has more.
Data and Graphs
- Sorting and Counting: Groups and Graphs
Sort objects into groups, count each group and put the groups in order, then read simple graphs to find the total and how many more or fewer. Grades K–1.
Geometry
- Building Shapes: Sides, Corners and Putting Shapes Together
Count the sides and corners of flat shapes, compare flat and solid shapes, build shapes with sticks and clay, and put small shapes together to make bigger ones.
- Shapes Around Us: Flat and Solid
Kindergarten geometry: name flat shapes of any size or turn, tell them from solid shapes like cubes and spheres, and use position words like above and next to.
