 In this first module of Grade 1, students make significant progress towards fluency with addition and subtraction of numbers to 10 (1.OA.6). They are presented with opportunities intended to advance...

 As students move into Topic B, they gain momentum with putting together, composing and decomposing, and counting on to determine the total. Students use both concrete and pictorial situations to...

 In Topic C, students develop a more robust understanding of addition word problems, moving beyond the Kindergarten problem types (K.OA.2) by reviewing put together with result unknown and add to with...

 Topic D affords students the opportunity to solve problems within the simplicity of equations, moving on from the context of story problems. Continuing on the momentum gained with counting on as it...

 Topic E leads students to a very intentional understanding and application of the equal sign and the commutative property of addition (1.OA.3 and 1.OA.7). Lessons 17 and 18 ask students to use...

 Topic F continues with the theme of more efficient strategies coupled with deep understanding to solve addition problems within 10. In Lesson 21, students begin to internalize doubles and doubles...

 Following the midmodule assessment, Topic G focuses on students understanding the meaning of subtraction as it relates to addition. In Lesson 25, students solve add to with change unknown problems...

 With a smooth transition from Topic G, Topic H provides students with rich experiences connecting subtraction to their solid foundation of addition (1.OA.4), using various word problem types (1.OA.1...

 Similar to Topic E’s addition methods, Topic I allows students to learn methods for subtraction which involve subtracting 0 and 1, subtracting the whole number, subtracting one less than the whole...

 Grade 1’s Module 1 closes with Topic J, where students spend Lesson 38 exploring the addition chart (similar to Topic F) and looking for patterns within the context of subtraction (MP.7, MP.8, 1.OA.6...

 Topic A begins with students solving word problems with three addends (1.OA.2) as a way for them to begin to explore the make ten Level 3 strategy in a meaningful context. With problems that always...

 Topic B focuses on the take from ten Level 3 strategy (1.OA.6). Students begin with word problems calling on them to subtract 9 from 10 in Lessons 12 and 13, first with concrete objects, then with...

 Topic C provides students with practice solving add to with change unknown, take from with change unknown, put together with addend unknown, and take apart with addend unknown word problems (1.OA.1...

 Topic D closes the module with students renaming ten as a unit: a ten (1.NBT.2a). This is the very first time students are introduced to this language of ten as a unit, so this is exciting! The unit...

 The module opens in Topic A by extending students’ kindergarten experiences with direct length measurement to indirect measurement whereby the length of one object is used to compare that of two...

 Topic B adds a new level of precision to measurement by introducing the idea of a length unit. In Lesson 4, centimeter cubes are laid alongside the length of objects as students learn that the total...

 Topic C gives students a chance to explore the usefulness of measuring with similar units. The topic opens with Lesson 7, where students measure the same objects from Topic B using two different non...

 Topic D closes the module as students organize, represent, and interpret personally relevant data in Lesson 10 (1.MD.4). As students work as a class to collect, sort, and organize data into a graph,...

 Module 4 builds on students’ work with teen numbers to now work within 40. Working within 40 helps students focus on the units, tens and ones, which can be easily modeled pictorially and concretely...

 Topic B begins with Lesson 7, where students identify the greater or lesser of two given numbers. They first work with concrete materials whereby they build each quantity (1.NBT.2) and find the...

 In Topic C, students pick up from their previous work with 10 more and 10 less to extend the concept to adding and subtracting multiples of 10. In Lesson 11, students represent the addition of ten...

 Topic D begins with students applying the Module 2 strategies of counting on and making ten to larger numbers, this time making a ten that is built on a structure of other tens. In Lesson 13,...

 As students begin working with larger numbers in word problems, representing each item and drawing it individually can become cumbersome. In previous work with problem types, the two parts have been...

 In Topic F, students begin adding like units within pairs of twodigit numbers. Lesson 23 focuses on taking interpretations of twodigit numbers a step further, having students interpret numbers such...
