MATH 0
Where the entire sequence stands.
Meridian Note
Target states are deliberately shallow: number names and counting sequence to KS-4; everything else KS-1 to KS-3. The single non-negotiable is cardinality — the last count-word names the quantity — pushed toward KS-6 through manipulative work, because every later state in the entire sequence stands on it.

Skills of This Course
Every skill is pinned to the meridian by fix notation — where along the scale, and at what depth. The highlighted state is this course's target: the state an honest instrument must certify before the skill counts as covered here.

Units
Unit 1.Counting Tells How Many
9 practice itemsCounting is a superpower. When you count, you find out how many. This unit shows you how to count the right way. It also shows you a big secret: the last number you say is special.

Unit 2.Numbers to 100
7 practice itemsNumbers go on and on! In this unit you will read numbers, say what comes next, and count all the way to 100 by tens. Big numbers are just little numbers with a pattern.

Unit 3.Putting Together and Taking Away
7 practice itemsMath can tell little stories. Some stories put things together — that is adding. Some stories take things away — that is subtracting. In this unit you will meet the + sign, the − sign, and the number zero.

Unit 4.Shapes All Around
7 practice itemsShapes are everywhere! Windows, wheels, balls, and boxes are all shapes. In this unit you will name flat shapes and solid shapes, and use words that tell where things are.

Unit 5.More, Fewer, Longer, Shorter
7 practice itemsWhich group has more? Which crayon is longer? Which rock is heavier? This unit shows you how to compare things fairly — with matching and counting, not just looking.
