 Topic C opens in Lesson 10 with students building a Rekenrek to 20, which they will use to count and model numbers for the balance of the year. They will deepen their understanding of the composition...

 Topic D leads students beyond teen numbers up to 100 (K.CC.1). They begin by counting up and down to 100 both the regular way (ten, twenty, thirty…) and the Say Ten way (ten, 2 tens, 3 tens…). In...

 Topic E’s Lesson 1 begins as students represent teen number decompositions and compositions by writing addition sentences. In Lesson 2, students make bonds with materials and hide one of the parts...

 In this final kindergarten module, students will extend and build upon their learning about two and threedimensional shapes from Module 2. Students use their knowledge about common features of...

 Thus far students have considered shapes independently, rather than in conjunction with other shapes. Topic B expands students’ thinking about shape by introducing the notion that simple shapes can...

 Topic F asks students to connect their understanding of number pairs for 9 and 10 to addition expressions and equations. Core Fluency Practice Sets and Sprints are introduced in this topic to give...

 Topic G provides additional practice with formal subtraction concepts, including writing and solving number sentences with totals of 9 or 10. Lesson 33 moves quickly through concrete and pictorial...

 In Topic H students will begin to see patterns when adding 0 and 1, and find the number that makes 10 when added to a given number (K.OA.4). Lesson 37 explores the additive identity: zero. Students...

 In Topic A, students count two separate parts within teen numbers, 10 ones and some ones. They start by counting piles of 10 straws to understand 10 ones. In the Lesson 2, students separate 10 ones...

 In Topic B, students advance to a more abstract level, representing the decomposition of teen numbers first with Hide Zero cards (Place Value cards) and in Lesson 2 with number bonds. They then work...

 In Module 1, students found embedded numbers and experienced decomposition by finding hidden partners. Topic A formally teaches composition and decomposition using number bonds as students explore...

 Topic B carries forward the work of Topic A, building students’ skill with number pairs for 6, 7, and 8, which is cultivated and maintained throughout Topics B and C during Fluency Practice. In the...

 Topic C introduces formal addition concepts including writing and solving expressions and equations. The first three lessons ask students to represent addition story problems involving decomposition...

 Topic D introduces formal subtraction concepts including writing and solving expressions and equations. Lesson 19 begins at the concrete level with students acting out take away stories and working...

 Topic E expands student exploration of numerical relationships to include 9 and 10. Returning to work with number bonds after introducing addition and subtraction provides students with a reminder...

 In Topic D, students compare volume in the same progression as that of weight in Topic C. In Lesson 13, they see that one container holds more rice than another by pouring the rice from the first...

 After the MidModule Assessment, the module shifts towards comparison of number, opening in Topic E with four lessons in which students consider, “Is there enough?” in a variety of contexts. Students...

 Topic F opens with students shifting from comparison of lengths to comparison of number. As students build their confidence by directly comparing the lengths of a pencil and a crayon, they are...

 Topic G is a bridge that enables students to compare numerals by connecting number to length. In Lessons 25 and 26, they work with linear configurations to match and count to see that “7 is more than...

 The module culminates with a series of three measurement and comparison exploration tasks. In Lesson 29, students compare volume by moving a constant amount of colored water between containers of...

 In Topic E, students’ engage in counting numbers above 5, namely 6, 7, and 8, in varied configurations. The students use their growing skill and knowledge of counting up to five to reason about...

 In this module, counting becomes more complex as the numbers get bigger. Throughout the module, the students learn to be flexible with numbers to 10. Students represent, count, and compare different...

 In the previous topics students counted lots of groups of threedimensional objects, concretely seeing that numbers represented quantities of those objects. Topic G transitions them to pictorially (...

 Topic H is a mirror image of Topic G. Students explored one more in Topic H and will explore one less in Topic G. In Lesson 33, the students use their knowledge of relationships between numbers to...
