Week 1: April 17

Notes:

Topic A, Working with Money, assumes that students have some knowledge about the coins from first grade and briefly reviews naming the coins and counting in the fluency activities in the lessons in Topic A. Consider providing additional opportunities to practice identifying coins and finding their total value throughout the topic. The final lesson (Lesson 5) in Topic A provides practice and working with money data as a segue to "problem solving with coins and bills" in Topic B.

Lessons 1 & 2 Combine

Lessons 1 & 2 share focus standard 2.MD.10 and have been combined as a pacing consideration. Lesson 2 guides students through creating a picture graph using the data from the tables created in Lesson 1. Follow Lesson 1 Concept Development to create Chart 3, Animal Classification. Include tallies and numbers in the table. Then guide students to organize the information into a picture graph as described in Lesson 2, Part 1 Concept Development. If time permits, work through the Lesson 2 Problem Set and assign Lesson 2 Exit Ticket.

Lessons 3 & 4 Combine

Lessons 3 & 4 share focus standard 2.MD.10 and have been combined as a pacing consideration. Lesson 3 follows the same procedure and uses the same data as in Lesson 2 to draw and label a bar graph. Begin with the Concept Development from Lesson 3, guiding students through creating a bar graph using the data from the Animal Classification table from Lessons 1 and 2. Complete the bar graph using the table, Our Birthdays from Lesson 4 Part 1 Concept Development. If time permits, work through Problem Set from Lesson 4 and assign Lesson 4 Exit Ticket.

Notes:

Lesson 11

Prior to the start of the lesson, create, display and reference an anchor chart that shows rectangles and circles partitioned into halves, thirds and fourths to capture the learning from Lesson 10. Use words half, third, and fourth to label each part to be consistent with the template provided in the lesson. Additionally, MP. 7, look for and make use of structure, is highlighted as students use one part to draw a whole. Guide them to recognize that all the parts are needed to make the whole.

Lesson 12 Omit

This lesson has been omitted as a pacing consideration. Students continue to explore the concept that equal parts of a rectangle can have different shapes. Previous lessons build students understanding that halves, thirds, and fourths are determined by the number of equal parts not by the orientation of the line.

Lesson 13

MP.3, construct viable arguments and critique the reasoning of others, is highlighted in Part 2 of the Concept Development as students make paper clocks and discuss partitioning the clock in halves and then fourths. Encourage students to use what they've learned about partitioning shapes into equal parts to describe the clock in preparation for telling time to the half and quarter hour. Consider creating and displaying an anchor chart with the features of an analog clock for students to reference as they practice telling time to the nearest half and quarter hour. Students will use their paper clocks in Lesson 14.

Lesson 14

MP.3, construct viable arguments and critique the reasoning of others, is highlighted in the Concept Development as students use skip-counting by fives to tell time to the nearest 5 minutes. Support students with using what they learned about fractions and the minutes to start at quarter past or 15, half past, or 30, quarter to or 45 and counting by 5 from there.

Administer End-of-Module Assessment after Lesson 14.

Lesson 15 Omit

This lesson has been omitted as a pacing consideration. It continues the same process of counting numbers on the clock face for the minute, and adds the complexity of a.m and p.m. Consider offering this as an extension for students.

Lesson 16 Omit

This lesson has been omitted as a pacing consideration. Students solve problems involving time intervals, where given two times, they must calculate how much time has passed between them. This previews the work of 3rd grade.
