**Before: **

1. To review and activate prior knowledge students will graph a line (given in slope-intercept form). Students will use their whiteboards with the coordinate plane and graph y = 3x + 2. The students will hold up their whiteboards as they finish and the teacher will assess their graphs.

2. Students will post the pictures that they brought from home at the front of the room (optional). Students will be given a few minutes to look at the pictures brought in by their classmates. The teacher will compare the pictures of students and their parents to "parent functions and their babies". The students can comment on how they are similar to their parents and how they are different from their parents.

**During:**

3. Students will use their digital devices to search for pictures of baby animals and their parents. Students will be given five minutes for this activity. The timer will be projected for students to see (See PowerPoint *5-down*). At the end of the five minutes students will share their favorite pictures. If students do not have access to an Ipad or computer the teacher may choose to show the PowerPoint "*Parents and Their Babies*".

4. The teacher and students will work through the PowerPoint "*It's All in the Family"* which will require the student to describe the changes that the functions undergo compared to the parent function. The PowerPoint concludes with a "one-minute paper" which will be completed and turned in at the end of the period.

5. Cooperative learning activity- Students will work in pairs. Students will use their whiteboards with the coordinate plane (graph paper could also be used). Each group will be given laminated cards of linear functions. One student will graph the linear function on the whiteboard and one student will compare the new function to the parent function. The students will then swap tasks. The teacher will walk around the room and assess the students understanding. (For suggested problems see attached "Linear Functions".)

**After: **

6. The students will have one minute to summarize what they have learned about building new functions. (This is found at the end of the PowerPoint "*It's All in the Family*".)
