This lesson continues the work with number riddles from the previous lesson. Students write their own riddles and then try to find each other’s secret number.
The cool-down should be completed before the lesson synthesis, as students will share their reflections with the whole class.
If students need additional support with the concepts in this lesson, refer back to Unit 4, Section B in the curriculum materials.
- Apply place value reasoning to write and solve number riddles.
