Module/Unit 1: Sums & Differences to 10

In this first module of Grade 1, students make significant progress towards fluency with addition and subtraction of numbers to 10 as they are presented with opportunities intended to advance them from counting all to counting on which leads many students then to decomposing and composing addends and total amounts. Students continue to use the Kindergarten strategy of number bonds to determine pairs of numbers that add to 10. In the context of addition to 10, students expand their knowledge of two basic ideas of mathematics: equality and the commutativity of addition. Students also learn that the equal sign is a symbol of the equality of two values, rather than that an equation represents an expression on one side and an answer on the other side. This understanding is foundational in allowing students to later construct true number sentences such as 4 + 3 = 3 + 4 without misunderstanding the equal sign to mean that the numbers are the same. Students create sets of related addition and subtraction facts and use dialogue to explain their found connections (e.g., 7 = 4 + 3, 7 – 4 = 3, 4 + 3 = 3 + 4, 4 = 7 – 3, etc.) They will also work with story problems, which help them understand addition and subtraction in relation to real world situations.
