Phase: | Before/Engage |
Activity: | Number talks are short mathematical discussions between the student, teacher, and classmates about how to solve a carefully chosen mental math problem. The students share their mathematical reasoning as the teacher records their thinking visually on the board or chart paper. Lead the class in a mathematical discussion using a number talk. 40 ÷ 4 16 ÷ 4 56 ÷ 4 These mental math problems will allow students to build on multiples of ten and find easy ways to divide within the dividend. This will help direct the students' thinking to use the partial quotients division strategy using the relationship between multiplication and division. Allow the students to share their thinking and mathematical reasoning to solve the problems. Once students have had an opportunity to share their thinking using the number talk, allow students to answer the journal prompt to continue their mathematical reasoning on the relationship between multiplication and division. |
Assessment Strategies: | Student discussions during the Number Talk and their responses on the journal prompt will be used as a formative assessment to identify if students can identify the relationship between multiplication and division and use it to find quotients of whole numbers. |
Advanced Preparation: | Students should have basic knowledge of multiplication and division. Teachers should have access to a whiteboard or chart paper. Students will need math journals. For more information on number talks, check out the book Number Talks by Sherry Parrish. |
Variation Tips (optional): | |
Notes or Recommendations (optional): | 12. Use strategies based on place value, properties of operations, and/or the relationship between multiplication and division to find whole-number quotients and remainders with one-digit divisors and up to four-digit dividends.
