Geometric Sequences Notes 8/31/15 INB 13

Homework for the week 8/31/15 to 9/4/15, click this link: Problem Sets #5 – 8

Do Now:  To begin class this week, we’ll be looking at non-linear visual patterns.

Visual Patterns 2 INB 11

For each VP  Describe the pattern.  Draw the next step.  Create a table for steps 1, 2, 3, 4, 10 and how many blocks needed to create the concrete model.  Either in words or using an algebraic equation, show how to find how many blocks are needed for Step 43.

INB 12 Arithmetic Sequences Notes Friday, 8/28/15

Friday – we checked Problem Set #4 and turned in the packet from the week.

Tuesday 8/13/13 Geometry

Recap Developing Definitions INB 19 from yesterday.  Ensuring we discuss the appropriate notation of terms.

In class, we partnered and played Blind Draw INB 16.  You had to choose a card containing one of the above figures, then give instructions to your partner and they tried to replicate it based solely on your directions.  If you were absent, choose 3 pictures and write your verbal directions on INB 16.

HW assignment:
1. write a reflection about the activity, tell what was hardest & easiest, why, for both roles of giving and receiving instructions.

2.  Create your own sketch, incorporating at least 1 point, 1 line, 1 plane and at least one other vocabulary term.  Include appropriate notations.  Cover your sketch with a post-it.

Write directions for your sketch.  I will give you feedback based on how closely I can draw your sketch using your directions.

INB 18  Draw What I Say

This page was similar to page 18, but is more scripted.  The focus is correct notation.

If you need a copy to complete the assignment please email me.

Have a parent or friend read the instructions and you draw the figures onto INB page 18. When complete, check your drawing against the answer on  the card.  Write a short reflection, what did you do well on, what do you need to improve?

Patty Paper exploration…

Use a straightedge to draw a segment with endpoints CD.

Fold C to D and crease your paper.

What do you see?  notice?

Label the point where the crease intersects CD, E.

How does CE compare to DE?  What does this tell you?

Compare the 4 angles formed…if I fold along thencrease, then fold along the segment, the 4 angles are congruent…90º.

So that means, j is a perpendicular bisector of CD.

Place a point, F, on j above CD.  Connect CF and DF with  straightedge.  What do you notice?

Place another point, G, on j above CD.  Connect CG and DG with a straightedge. What do you notice?

Place another point, H, on j below CD.  Connect CH and DH.  What do you notice?

Will this always be true?

INB 15 Segments & Midpoints

INB 14 Part 1 Processing Midpoints of Segments (boss/secretary) Part 2 Segment Addition practice page 8

INB 17 Midpoints with Coordinates

After some sharing of how to find the midpoints with graph paper – another student suggested he added the coordinates, then divided by 2.

Find M, the midpoint of AB.  A(7, 3) and B (13, 5)…

x-coordinates:  7+13=20 / 2 = 10 and y-coordinates:  3 + 5 = 8 / 2 = 4 so the midopint will be M(10, 4)
