Cluster: Working with numbers 11-19 to gain foundations for place value. Standards Key ideas and Details Intervention Supports K.NBT.1 Compose and decompose numbers from 11 to 19 into ten ones A – and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or ML – equation (e.g., 18 = 10 +8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, ML – eight, or nine ones. Grade 1 Cluster: Extend the counting sequence. Standards Key ideas and Details Intervention Supports 1.NBT.1 Count to 120, starting at any number less than 120. In this range, ML – read and write numerals and represent a number of objects with a written numeral. ML – Cluster: Understand place value. Standards Key ideas and Details Intervention Supports 1.NBT.2 Understand that the two digits of a two-digit number represent PL – amounts of tens and ones. Understand the following as special cases: A – a. 10 can be thought of as a bundle of ten ones — called a “ten.” V – b. The numbers from 11 to 19 are composed of a ten and one, two, three, four, five, six, seven, eight, or nine ones. ML – 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 ML – (and 0 ones). A –
