Levels and Common Core standards.

Every level, kindergarten to 5th grade, with the Common Core State Standards it practices. Each grade has 8 levels. A level adds question types to the ones before it, and levels open as the student gets them right. The first level of each grade reviews last year. If your state has its own standards, compare them with this list.

Kindergarten

Level 1: Counting up to 10
e.g. 4, 5, 6, ? and the biggest of 8, 7, 6
Numbers: 1 to 10
Standards: K.CC.1, K.CC.2, K.CC.6, K.CC.7
K.CC.6 is the closest standard for picking the biggest number. It compares groups of objects, and K.CC.7 compares written numbers.
Level 2: Counting up to 20
e.g. 13, 14, 15, ? and the biggest of 17, 16, 15
Numbers: 1 to 19
Standards: K.CC.2, K.CC.6, K.CC.7
K.CC.7 is the closest standard for comparing numbers here. It stops at 10, and this level goes to 19.
Level 3: Addition, sums up to 5
e.g. 2 + 3, 1 + 4
Numbers: sums 2 to 5
Standards: K.OA.1, K.OA.5
Level 4: Subtraction, from 5 or less
e.g. 5 − 2, 4 − 1
Numbers: from 2 to 5
Standards: K.OA.1, K.OA.5
Level 5: Missing number, sums to 5
e.g. 3 + ? = 5, 4 + ? = 5
Students find the number that finishes 5.
Numbers: pairs that make 5
Standards: K.OA.3
Level 6: Missing number, sums to 10
e.g. 3 + ? = 10, 7 + ? = 10
Students find the number that finishes 10.
Numbers: pairs that make 10
Standards: K.OA.4
Level 7: Addition, sums up to 10
e.g. 6 + 3, 4 + 5
