By end 9–14, 16–23, 26-1, 26-2, 26-3, of Grade 2, know frommemory all sums of two one-digit numbers. 33 26-4, 27-1, 27-2, 28-1 to 28-4, 29-1, 29-2, 29-3 33-1 Workwith equal groups of objects to gain foundations formultiplication. 2.OA.3 Determinewhether a group of objects (up to 20) has an odd or 7, 8 9-2, 9-3, 9-4, 9-5 even number f members, e.g., by pairing objects or counti g them 26-4 by 2s; write an equation to express an even number as a sum of two equal addends. 2.OA.4 Use addition to find the total number of objects arranged in 66 50-2 rectangular arrayswith up to 5 rows and up to 5 columns; write an equation to express the total as a sum of equal addends. Number andOperations in Base Ten Understand place value. 2.NBT.1 Understand that the three digits of a three-digit number represent 41, 42 45-1 to 45-7 amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens and 6 ones. Understand the following as special cases: 2.NBT.1.a 100 can be thought of a bundle of ten tens – called a 'hundred." 25 45-1, 45-3, 45-4, 45-5, 45-7 2.NBT.1.b The numbers 100, 200, 300, 400, 500, 600, 700, 800, 900 refer to 41, 42 45-1 to 45-7 one, two, three, four, five, six, seven, eight, or nine hundreds (and 0 tens 0 ones). 2.NBT.2 Count within 1000; skip-count by 5s, 10s, and 100s. 6, 24, 25, 41 10-1, 45-1, 45-3 to 45-7 2.NBT.3 Read andwrite numbers to 1000 using base-ten numerals, 5, 25, 27, 41, 4-1, 4-2, 8-1, 8-2, number names, and expanded form. 42 11-1, 11-2, 45-1 to 45-7, 46-1 Correlation toCommonCoreContentandPracticeStandards, ExtensionsGrade2 Use this table tomatchobjectives topages in the Student Book and Skill Builders.
