Midpoint G.3a Obj: SWBAT find the midpt on a number line & coordinate plane (1.7) Warm-up: “Terms Segments Lengths/Midpoints” (1-15o) **hw/hw log/Storybook Homework (day 4): “Terms, segments, Lengths/Midpoints” worksheet Storybook due next block/Bring Graph paper Write a goal for the 1st NW in your storybook Pearsonsuccess due Friday Quiz next block (more Alg I skills, 1.2, 1.3,1.7)

Admin Notes: It is imperative that you if you did not earn at least an 80% on your quiz day 3 (Algebra I)- you must come for extra help! Your first and last name and block must be on each paper you turn in! If your paper says “WHO,” then you must bring it back to me with your name on it. Honors: online pearsonsuccess.net assignments due Friday (there are no late online grades) Remember to assemble your storybook for your first class grade!!!!! Tab p. 7 in your storybook to begin using as a reference

Midpoint of a Segment on a coordinate Plane ”MAD” = midpoint, add, divide

Let’s Practice- graph Paper in front of room Given: C(-3,0) D(-3,-4) Midpoint AB (2, 1) 10. AB 11. (0, -1) 12. AC A B

Finding the missing value(s) 16. Find the missing endpoint of where M is midpoint (4,-1) and J(3,2). Find the coordinates of K, using graph paper. (5, -4) 17. The midpoint is (-1, 0) and one endpoint is (-5,-6). Find the missing endpoint, algebraically. (3, 6)

Extra Practice: 19. Find the coordinates of the missing endpoint of when M(-1,-2) and one endpoint is W(4,4). Find the coordinates of V. (Hint: Graph and label the points)

Extra Practice: Find the length of , where A(-3, 2) and B(1, -4)
