• ## Lesson Plan

• Subject: Math
• Driving Question: How do we regroup in addition?
• Pedagogical Method: Inquiry-Based Learning
• Duration: 80 minutes / 2 sessions
• Delivery Method: Synchronous Virtual
• ### Purpose:

Students will be able to use regrouping as a method in addition.

• ### Before you start

Materials: laptops/tablets/Mobile phones with Internet Connection

• ### Objectives

• Students will be able to use different strategies to add.
• Students will be able to add 2-digit numbers with and without regrouping.
• Students will be able to solve word problems involving addition.

• ### Prior Knowledge

• Students are able to recognize that addition is adding more to a given amount.
• Students are able to count forward.
• Students are able to use mental math strategies to add doubles and partners of 10.

• ### Warming Up

• Project Worksheet 1 and ask the students to choose the problem they want to solve. It is important for students to know that they can use any strategy they wish.
• Divide the students into different breakout rooms. Inform them that in the breakout room, those who solved Exercise 1 will share their strategies together, those who solved Exercise 2 will share their strategies together.
• Check in with each group and take notes of some keywords shared and questions and misconceptions popping up.
• ### Learning Activity 1

• Referring to the different strategies shared, announce that the students will now add to their bank of strategies, a new one to help them add greater numbers.
• Project Link 1 and model representing the two numbers in one of the word problems.
• Ask the students to count the number of ones there are in total and think about what can be done with them (regroup into tens).
• Model regrouping 10 ones into 1 ten.
• Have students use Link 2 to consolidate their understanding by watching the video and listening to the song.
• To check for understanding, have students access Link 3 to take the quiz.
• ### Learning Activity 2

• Share Link 4 with students to play a nice Archery game as they practice regrouping in addition for two-digit numbers.
• To check for understanding, send Link 5.
• ### Wrap-Up

• Refer back to students’ questions at the beginning of the session and have volunteers share answers to some of them. Have students reflect on how their learning is shaping up by saying, “I used to think…Now I know…”
• For the assessment, refer to Test 1 and Answer Key 1
