Unit 1, Lesson 11, Activity 3. The IQR for restaurant A is 2.5.
Unit 2, Lesson 14, Activity 2. The solution for question 3 now uses the variable \(t\) instead of \(r\).
Unit 2, Lesson 15, Activity 3. In the statement for Jada's situation, the question is updated to, "...2 dollar coins weigh 16.2 grams?" and the solution to say, "...16.2 more grams."
Unit 3, Lesson 8, Activity 2. The order of the graphs in the student statement was incorrect. Graph A is the one referencing sleep and energy, graph B references hair and energy, graph C references school events and videos, and graph D references temperature and watermelon.
Unit 4, Lesson 12, Activity 2. Question 2 now says the child is 35 months old. The solution to 3b is 0, 4, 6, 9, 10.
Unit 5, Lesson 1, Activity 2. The way Tyler was saving money did not match the values given in the table and solution. The prompt has been updated to show that Tyler saved \$2 the first two weeks and doubled the amount saved each week thereafter.

Unit 6, Lesson 1, Activity 2. The third question now asks for a rectangle with the same perimeter and greater area than the previous answer.
Unit 6, Lesson 4, Activity 2. The first question referred to the equation \(3x^2\) instead of \(3 \boldcdot 6^x\). The question is updated to \(3 \boldcdot 6^x\) to match the table and solution.
Unit 6, Lesson 9, Activity 2. In the solution for question 3, the last term of the first expression is \(5 \boldcdot \text-m\)
Unit 6, Lesson 17, Activity 1. The instructions now refers to triangle \(PQR\). The sample response for A is updated to, "...is not an identical copy."
Unit 7, Lesson 12, Activity 3. The solution to 2h is 6.
Unit 7, Lesson 19, Activity 1. The first equation now appears only once and the last sentence of the solution is updated to, "The second line should be..."
Lesson Numbering for Learning Targets
In some printed copies of the student workbooks, we erroneously printed a lesson number instead of the unit and lesson number. This table provides a key to match the printed lesson number with the unit and lesson number.
