## Tips for Teachers

?

• Lesson 25 is intended to address the cluster level expectations for 3.NF.A, namely, “develop understanding of fractions and numbers.” Since Anchor Task #1 is quite extensive, it is the only Anchor Task for the lesson. The lesson could consist entirely of the discussion regarding Anchor Task #1, or a Problem Set and Homework can be designed to review much of the work of the unit. The Target Task is optional, as well, depending on whether Part B of Anchor Task #1 feels sufficient for students to demonstrate their understanding of fractions as numbers.
• There is no Problem Set assigned for this lesson. The first task linked below is aligned to today’s objective. The rest of the resources are more of a comprehensive review or performance task addressing all of the content throughout the unit thus far. It is at your discretion which resources, if any, you use to create a Problem Set and Homework.
