Lesson 4

Consider chunking the Concept Development into two mini-lessons with guided practice & work time. Support students in discovering what happens to the difference when adding the same amount to each number in a subtraction sentence. Then work with students to use the make ten strategy with larger numbers to solve addition problems. Customize the problem set so that students practice both strategies. Ask, "When is the best time to use the tape diagram to solve? What is the goal in using the tape diagram as a simplifying strategy?", from the Student Debrief to close the lesson.

Lesson 5

MP.1, make sense of problems and persevere in solving them, is highlighted in this lesson. Support students with using the RDW process by adhering to the suggested delivery of instruction for solving word problems. Remind students of the strategies (tape diagrams, arrow way, number bonds, etc) that they've learned thus far and help them to decide which strategy works best for them as they work to solve each problem. *Use the Exit Ticket as the biweekly to assess student's application of the strategies to add and subtract multiples on 10 and some ones.

Lesson 6

MP.4, model with mathematics, is highlighted in the Concept Development as students use place value disks on a place value chart to represent the composition of 10 ones as 1 ten with two-digit addends. Model and encourage arranging disks in 5-groups so that students can easily see the composition of 10.

Lesson 7

MP.4, model with mathematics, is highlighted in the Concept Development as students use place value disks to model addends. Support students with relating the disks to the vertical form by modeling and encouraging the use of place value language to describe manipulating the disks and recording each step in vertical form.

MP.6, attend to precision, is highlighted in the Concept Development as students draw unlabeled place value charts with labeled disks to represent addition and record each step in the vertical form. Model and teach students to align digits in the proper place, draw place value disks in 5-groups, and show new groups in the correct place. Continue to support students with relating their models/drawings to the vertical form and use and encourage the use of place value language to describe each step.

Lesson 9

Students are introduced to the chip model (dots on a labeled place value chart) and transition from using unlabeled place value charts with labeled disks. Continue to have students attend to precision, MP.6, as they model drawing and recording steps in the vertical form. Have students use place value language as they explain how their models match the vertical form.

Lesson 10

This lesson shares focus standard 2.NBT.9 and the objective with Lesson 9 and offers additional practice using place value disks, disk drawings, and chip models. As students work with their partners to write, model, and solve addition of 2-digit to 3-digit problems, have them check their work and use place value language to explain how their models and numbers show the algorithm to address MP.3, construct viable arguments and critique the reasoning of others.

Lesson 11

MP.4, model with mathematics, is highlighted in the Concept Development as students are guided through the process of using place value disks on a place value chart to subtract like units by decomposing. Describe how modeling subtraction means representing the whole and find a missing part and reinforce this idea with each example. Ask, "How do you know when you must unbundle a ten to subtract?", from the Student Debrief to prepare students for looking carefully at the whole when subtracting in follow up lessons.

Week 6: December 11

Notes:

Lesson 12

MP.2, reason abstractly and quantitatively, is highlighted in the Concept Development. Remind students to only show the whole when solving subtraction problems with place value disks and invite them to explain why. Support students with modeling each subtraction problem with disks and recording that work in the vertical form. Consider prioritizing Problem 2 from the Problem Set as it provides students an opportunity to analyze an error and explain their thinking.

Lesson 13

Lesson 13 builds on the work done in the previous two lessons. Invite students to guide you through the steps of modeling and recording in vertical form to address MP.2, reason abstractly and quantitatively. Consider data from Lesson 12 Exit Ticket and provide additional practice solving using place value chips prior to transitioning to the chip model.

Lesson 14

Encourage the use of place value language as students describe how their models match the vertical form when solving subtraction problems. Have students attend to precision, MP.6, as they draw their chip models, creating 5-groups and aligning them in the correct place and as they record each action in the vertical form. Consider asking, "How did having a three-digit addend change the way you solved the problem?", from the Student Debrief to get students thinking about the cyclical process of decomposing.

Lesson 15

Lesson 15 shares focus standards 2.NBT.7 and 2.NBT.9 and the objective with Lesson 14 and offers additional practice using place value disks and chip models to solve subtraction problems. As students work with their partners to write, model, and solve subtraction when there is a 3-digit minuend, have them check their work and use place value language to explain how their models and numbers show the algorithm to address MP.3, construct viable arguments and critique the reasoning of others. *Use the Exit Ticket as the biweekly to assess students' understanding of solving subtraction with and without decomposition.

Week 7: December 18

Notes:

Lesson 16

Support students with using the RDW process by adhering to the suggested delivery of instruction for solving word problems.

Lesson 21

This lesson shares focus standard 2.NBT.7 and the objective with Lesson 20 and offers additional practice using chip models to solve additions with up to two compositions. Consider introducing the concept of “Totals Below” from Lessons 29 & 30 in Lesson 21. Continue to embed “Totals Below” in the Concept Development or in the Debrief of subsequent lessons.

Week 9: January 15

Module

Notes:

Lesson 22

MP.3, construct viable arguments and critique the reasonableness of others, as students use multiple strategies for composing and decomposing numbers and properties of operations to add numbers in an order that is easiest to compute. Guide students to talk with each other about their solution strategies using place value language.

Lesson 23

Help students make the connection to the Take from the Ten Fluency Activity as it acts as a foundation for subtracting from the hundred. MP.2, reason abstractly and quantitatively, is highlighted as students break apart three digit minuends and subtract from the 100.

Lesson 24

Guide students to use place value disks to unbundle the hundred before subtracting, MP.4, model with mathematics, just as they unbundled a ten for 10 ones. Consider customizing the Problem Set with "must do" and "try this" problems depending on students' proficiency.

Module

Topic

Notes:

Lesson 25

Allow students to work in partnerships and take turns modeling decompositions on their place value charts with place value disks and recording in the vertical form. As students work, remind them to carefully look at each place in the whole to determine if unbundling is needed. Model and encourage the use of place value language to describe each step in the process to address MP.2, reason abstractly and quantitatively.

Lesson 26

Lesson 26 provides additional practice solving subtraction problems with up to two decompositions. Guide students to attend to precision, MP.6, as they transition from place value disks to drawing chip models and recording changes in the vertical form. If students struggle with the transition, provide more support with using the disks. Likewise, offer support to students who are ready to shift from concrete models to solving with just the written form.

Lesson 27

MP.4, model with mathematics, is highlighted in the Concept Development. Guide students with representing hundreds with the fewest disks and again by unbundling tens and ones. Discuss with students how this is helpful when subtracting from a number with 0 in the ones and/or tens place.
