Lesson Idea: Video Recording

Grade/Subject: Grade 5, Math

Lesson Topic: Adding and Subtracting Strategies

Lesson Duration: 50 minutes



Curriculum Expectations:

• Overall: Read, represent, compare, and order whole numbers to 100000, decimal numbers to hundredths, proper and improper fractions, and mixed numbers

• Specific: 
• Solve problems involving the addition, subtraction, and multiplication of whole numbers, using a variety of mental strategies. 
• Use estimation when solving problems involving the addition, subtraction, multiplication, and division of whole numbers, to help judge the reasonableness of a solution 

Learning Goal:
Students will be able to demonstrate knowledge of a mental strategy for addition or subtraction. Students will be able to use estimation to check the reasonableness of an answer.


Modification/Accommodation:

• Modification: Students will work with numbers smaller than 50; student and teacher will select and work through strategy with assistance from peer group; students will use pencil-and-paper methods 
• Extension: Students will be asked to present their answer using another strategy in order to check their answer

Pre-Lesson:
Teacher will ask students to watch the short math problem videos (Video 1, Video 2) they created. Students will consider the following questions about the videos: What is the math problem that is being presented? What information do we need to solve this problem? What strategies will help us in solving this problem? What information is shown to us in the second video?


Setting the Stage:
With the class, the teacher will review the videos. The teacher will unpack the problem with the answers that the students had already brainstormed. Students will discuss predicting and estimating, and how this information will inform our answer (since we are unable to find the exact number of lego)

Students will set a plan as a class, and the teacher will check for understanding


Core Learning:
Using their iPads, students will use pictures and manipulatives to represent their ideas and answer to the problem. Students will use 2 mental strategies to solve the equation (and check their answer). Students will discuss which calculations were performed mentally, though all should be recorded in the final submission.

Debriefing:
Via Airplay, students will project their answers and the class will discuss using mental strategies through videos.


Post-Lesson:
For a following lesson, students will design and film their own math video. The students will share these videos with the teacher, which will be given to the class to solve. The students must roughly know the correct number of materials present in their video.


Assessment:
For Learning - student responses; student understanding of mental strategies and estimation
Of Learning - Student submissions; use of strategies and estimation
