For the bar model below, if chocolates are considered 90 units, explain how you would determine the number of units equal to candy sticks. 

Select the equation that is true about the bar model shown below.

Question 1: You have moved into your first apartment with a group of housemates and created a household chore chart. Your first assigned tasks are to clean: The exterior glass windows (covered in grease and dirt). The inside of the porcelain toilets (covered in hard-water mineral scaling/calcium carbonate). Using your knowledge of acids, bases, and chemical properties, explain what type of cleaning product (acidic, basic, or neutral) you would choose for each task and why. Windows Product Type & Why: _____________________________________ Toilet Product Type & Why: _____________________________________

Choose the expression that best answers the question posed in the bar model below.

Write a paragraph explaining what the polynomial means, what it looks like using chip charts and base blocks, and how it connects to mathematics topics in elementary curriculum.

Match each of the polynomial models shown below with one of the polynomials listed here:

Below you will find a division algorithm and another copy of it with numbered quantities. You are encouraged to work through the problem with your algebra tiles before solving. Decide which labeled quantity tells you how much of the polynomial’s total area was placed inside the rectangle after accounting for the area composed of (x – 4) and -2.

The picture below shows how you would set up an open box method for multiplying (x2 + 5x)(x2 – x – 4).  Explain how you would determine the value of each of the spots in the model #1-7. Figure long description (click to reveal) Open box is displayed with six cells in the table arranged in a two by three formation.  Outside the box moving down the left side, the labels of x-squared and 5x are shown.  The box is labeled across the top moving left to right as x-squared, -x, and -4.  The cells are numbered across the top 1, 2, 3 moving from left to right and then across the bottom 4, 5, and 6 moving from left to right.  Below the box is the text that reads “Final Answer:” and a label of seven.  

Select the statements that are true about applying the “finding the difference” interpretation of subtraction to the subtraction of
