10. Design and Organization
Standards define what students should understand and be able to do. Clusters are groups of related standards. Note that standards from different clusters may sometimes be closely related, because mathematics is a connected subject. Domains are larger groups of related standards. Standards from different domains may sometimes be closely related. Extend the properties of exponents to rational exponents. 1. Explain how the definition of the meaning of rational exponents follows from extending the properties of integer exponents to those values, allowing for a notation for radicals in terms of rational exponents. 2. Rewrite expressions involving radicals and rational exponents using the properties of exponents.

20. Question:
A class needs 5 leaves each day to feed its 2 caterpillars. How many leaves would they need each day for 12 caterpillars?

21. Turn and Talk
How might students solve this problem correctly by finding the number of leaves needed for 1 caterpillar?
A student gets an answer of 15. What questions could be asked to get to the correct answer?
How might students solve this problem correctly by counting by 2’s and 5’s?
How might students incorrectly use additive reasoning to solve this problem?

27. Mathematical Practices

28. Reason abstractly and quantitatively.

29. Mathematically proficient students make sense of quantities and their relationships in problem situations.
They bring two complementary abilities
The ability to decontextualize—to abstract a given situation and represent it symbolically and manipulate the representing symbols as if they have a life of their own, without necessarily attending to their referents
The ability to contextualize, to pause as needed during the manipulation process in order to probe into the referents for the symbols involved.
Quantitative reasoning entails habits of:
creating a coherent representation of the problem at hand
considering the units involved
attending to the meaning of quantities, not just how to compute
knowing and flexibly using different properties of operations and objects

Write a complete sentence to describe what this sign is communicating.

31. The speed limit is 55 miles per hour
The speed limit is 55 miles per hour. Now, write this sentence as a ratio.

32. 55 miles : 1 hour 55 miles to 1 hour
55 miles to 1 hour
55 miles : 1 hour
What does the word “per” refer to in 55 mph?
Express 55 mph as a maximum limit using an inequality.

33. Complete the following table.
HOURS
MILES 1 55 2
165 5
275
Estimate the quantity of miles traveled in 90 minutes and explain your reasoning.
Predict the quantity of time in minutes if you traveled 440 miles.

34. Create a complete graph from the table
Do you expect to have data in the third quadrant?
Justify your response with complete sentences.

35. I don’t expect data in the third quadrant because time is not negative nor is distance traveled.
