# Coding Tessellations

Directions: Using the following command blocks (at most one time each):

Create code that will produce the following image:

Do you need all of the command blocks?

Is there a more efficient way to produce the code?

# Coding Shapes- Open Middle Problem

Directions: Create code that will make a regular polygon.  You can only use command blocks once and the digits 0-9 once to fill each box.

The polygon this makes is a ____________________

# 2- Way Frequency Table- Open Middle Problem

Directions: Using the digits 1 to 9, at most once each, fill in the boxes in this two way frequency table to make the statements true.

1. Students were four times as likely to wear low athletic shoes than high casual shoes

2. Three-sevenths of the students who wear low shoes wear casual ones.

3. More students wore athletic high tops than casual shoes

Other Questions:

How many students were surveyed?

Can you find the probability that a student is wearing any of the shoe choices?

What does this data tell you?

# Line of Best Fit- Open Middle Problem

Directions: Using the digits 0 to 7, at most once each time, fill in the blanks to create a scatter plot with line of best fit y= 1/2x + 4.

(___ , ___) (___ , ___) (___ , ___) (___ , ___)

# Irrational Approximations on a Number Line

Using the numbers 1 to 9, each only once, label the following number line.

Graph the roots of the first nine roots (e.g. √1, √2, … √9) on your number line.

What do you notice?  What do you wonder?

(I’m wondering how I can make a good OM problem out of this, should I keep the boundaries of 1 to 9 ?  Have students find a root that lies between each integer?)

# Approximating Irrational Numbers- Open Middle Problem

Directions: Using the integers 2 to 8, at most once each time, fill in the boxes to make the graphic true.

Are there any places you know certain numbers have to be on the graphic? How do you know?

# What’s Missing- Nature

What’s Missing?  Why?
