1. Unit 2 Day 8 FOCS – Human Computer Interaction

2. Journal Entry: Unit #2 Entry #7 Cornrow Reflection Describe each step of the problem solving process that you used to create your design. Highlight mathematical concepts such as iteration, translation, dilation, and reflection that you used and where and how they are used.

3. Cornrow Presentations Powerpoint has a title slide with group members names, period, and group number (10 pts) Choose a braid design from one of the design pictures to recreate Each design has a minimum of 4 separate braids (40 pts) Each design has an explanation of the mathematics behind the design including (50 pts): Translation, Rotate, Dilate Starting Point, Starting Angle, Reflection (X/Y), Starting Translation Iteration # Any group member that leaves their area will lose points for their group

4. Binary Representation 1, 10, 100, 1000, 10000 What do these numbers have in common? 1, 2, 4, 8, 16 What do these numbers have in common? How many numbers can you represent with a 3 digit (decimal) number How many numbers can you represent with a 3 digit (binary) number?
