For 2nd graders, we will:
focus instructional efforts in intervention first on Foundational Number Ideas to 20, regardless of which iReady Diagnostic domain score is lowest, to ensure students have a solid foundation on number ideas to 20
Students scoring at Grade K will need concrete examples using manipulatives and visuals to help bridge their access to this content.
utilize the topic's progression in conjunction with iReady reports and classroom data to determine best entry point
Timing of grade levels units should not impact intervention content for 2nd grade.
Major topics for intervention are listed below in the shaded section bars. Under each topic are the standards clusters associated for that content. Click the drop downs to find the standards under that cluster and the related Tools for Instruction. Use your student data and the progression of the standards to target the best starting place for the group of students you have for math intervention.

a. When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object.
b. Understand that the last number name said tells the number of objects counted. The number of objects is the same regardless of their arrangement or the order in which they were counted.
c. Understand that each successive number name refers to a quantity that is one larger.
Count to answer "how many?" questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1–20, count out that many objects. (K.CC.B.5)

Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.2 (1.OA.A.1)

Find the Rule
Apply properties of operations as strategies to add and subtract. Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.) (1.OA.B.3)
Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8. (1.OA.B.4)

Relate counting to addition and subtraction (e.g., by counting on 2 to add 2). (1.OA.C.5)
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).

Understand that the two digits of a two-digit number represent amounts of tens and ones. Understand the following as special cases:
a. 10 can be thought of as a bundle of ten ones — called a "ten."
b. The numbers from 11 to 19 are composed of a ten and one, two, three, four,
five, six, seven, eight, or nine ones.
c. The numbers 10, 20, 30, 40, 50, 60, 70, 80, 90 refer to one, two, three, four,
five, six, seven, eight, or nine tens (and 0 ones). (1.NBT.B.2)
