How to Use a Math Medic Answer Key

Written by Luke Wilcox published 3 years ago

Answer key might be the wrong term here. Sure, the Math Medic answer keys do provide the correct answers to the questions for a lesson, but they have been carefully designed to do much more than this. They are meant to be the official guide to teaching the lesson, providing specific instructions for what to do and say to make a successful learning experience for your students.

Before we look at the details of the answer key, let's make sure we understand the instructional model first.

Experience First, Formalize Later (EFFL)

A typical Math Medic lesson always has the same four parts: Activity, Debrief Activity, QuickNotes, and Check Your Understanding. Here are the cliff notes:

Activity: Students are in groups of 2 - 4 working collaboratively through the questions in the Activity. The teacher is checking in with groups and using questions, prompts, and cues to get students to refine their communication and understanding. As groups finish the activity, the teacher asks students to go to the whiteboard to write up their answers to the questions.

Debrief Activity: In the whole group setting, the teacher leads a discussion about the student responses to the questions in the activity, often asking students to explain their thinking and reasoning about their answers. The teacher then formalizes the learning by highlighting key concepts and introducing new vocabulary, notation, and formulas.

QuickNotes: The teacher uses direct instruction to summarize the learning from the activity in the QuickNotes box - making direct connections to the learning targets for the lesson.

Check Your Understanding: Students are then asked to apply their learning from the lesson to a new context in the Check Your Understanding (CYU) problem. This can be done individually or in small groups. The CYU is very flexible in it's use, as it can be used as an exit ticket, a homework problem, or a quick review the next day.

How Do I See EFFL in the Answer Key?

You will see EFFL in the answer key like this:

Anything written in blue is something we expect our students to produce. This might not be quite what we expect by the end of the lesson, but provides us with a starting point when we move to formalization.

Anything written in red is an idea added by the teacher - the formalization of the learning that happened during the Activity. Students are expected to add these "notes" to their Activity using a red pen or marker.

What Do Students Write Down For Notes?

By the end of the lesson, students will have written down everything you see on the Math Medic Answer Keys. The most important transition is when students finish the Activity and we move to Debrief Activity. "Students, now is the time for you to put down your pencils and get out your your red Paper Mate flair pens" We give each student a Paper Mate flair pen at the beginning of the school year and tell them they must cherish and protect it with their life. They all think we should be sponsored by Paper Mate (anyone have any leads on this?)

The lessons you see on Math Medic are all of the notes we use with our students. We do not have some secret collection of guided notes.

Do Students Have Access to Answer Keys?

Yes! Any student can create a free Math Medic account to get access to the answer keys. We often send students to the website when they are absent from a lesson or when we don't quite finish the lesson in class. We are comfortable with students having access to these answer keys because we do not think Math Medic lessons should be used as a summative assessment or be used for a grade (unless it's for completion). Our lessons are meant to be the first steps in the formative process of learning new concepts.

Texas Go Math Grade 7 Lesson 1.1 Answer Key Rational Numbers and Decimals

Texas Go Math Grade 7 Lesson 1.1 Explore Activity Answer Key

B. Now find the corresponding fraction of the decimal equivalents given in the last two columns in the table. Write the fractions in simplest form.

C. Conjecture What do you notice about the digits after the decimal point in the decimal forms of the fractions? Compare notes with your neighbor and refine your conjecture if necessary.

Question 1. Consider the decimal 0.101001000100001000001… Do you think this decimal represents a rational number? Why or why not? Answer: This decimal. number does not represent a rational number because it racks a repeating pattern.

Go Math Grade 7 Lesson 1.1 Rational Number Answers Question 2. Do you think a negative sign affects whether or not a number is a rational number? Use –\(\frac{8}{5}\) as an example. Answer: No, a negative sign does not affect whether or not a number is a rational number. – \(\frac{8}{5}\) = \(\frac{-8}{5}\) No, – \(\frac{8}{5}\) = \(\frac{-8}{5}\)

EXPLORE ACTIVITY (cont’d)

Question 3. Do you think a mixed number is a rational number? Explain. Answer: Yes, a mixed number is a rational number because it can be written as a simpLe fraction. For exampLe, 2 \(\frac{1}{4}\) = \(\frac{9}{4}\)

Write each rational number as a decimal.

Texas Go Math Grade 7 Lesson 1.1 Guided Practice Answer Key

Write each rational number as a decimal. Then tell whether each decimal is a terminating or a repeating decimal. (Explore Activity and Example 1)

Write each mixed number as a decimal. (Example 2)

Essential Question Check-In

Question 18. Tom is trying to write \(\frac{3}{47}\) as a decimal. He used long division and divided until he got the quotient 0.0638297872, at which point he stopped. Since the decimal doesn’t seem to terminate or repeat, he concluded that \(\frac{3}{47}\) is not rational. Do you agree or disagree? Why? Answer: Tom was wrong to conclude that \(\frac{3}{47}\) is not rational. First of all. \(\frac{3}{47}\) is a fraction. Thus, \(\frac{3}{47}\) is a rational number. After some time of long division, the patter would appear. I disagree. \(\frac{3}{47}\) is a rational number.

Texas Go Math Grade 7 Lesson 1.1 Independent Practice Answer Key

Go Math Grade 7 Lesson 1.1 Answer Key Grade 7 Question 25. Yvonne bought 4\(\frac{7}{8}\) yards of material to make a dress. a. What is 4\(\frac{7}{8}\) written as an improper fraction? Answer: 4 × 8 + 7 = 39 4\(\frac{7}{8}\) = \(\frac{39}{8}\)

c. Communicate Mathematical Ideas If Yvonne wanted to make 3 dresses that use 4\(\frac{7}{8}\) yd of fabric each, explain how she could use estimation to make sure she has enough fabric for all of them. Answer: Yvonne could multiply 4\(\frac{7}{8}\) by 3 and then buy some more yards (1 or 2) of fabric to ensure she would have enough to make 3 dresses.

Question 26. Vocabulary A rational number can be written as the ratio of one _________ to another and can be represented by a repeating or ________ decimal. Answer: A rational number can be written as the ratio of one integer to another and can be represented by a repeating or a terminating decimal.

Question 29. Analyze Relationships You are given a fraction in simplest form. The numerator is not zero. When you write the fraction as a decimal, it is a repeating decimal. Which numbers from 1 to 10 could be the denominator? Answer: The denominator could be a prime number (except 2 and 5) or a number that has a prime number in its factored form (again except 2 and 5). These numbers from 1 to 10 are: 3, 6 = 2 × 3, 7, 9 = 3 × 3

Question 30. Communicate Mathematical Ideas Julie got 21 of the 23 questions on her math test correct. She got 29 of the 32 questions on her science test correct. On which test did she get a higher score? Can you compare the fractions \(\frac{21}{23}\) and \(\frac{29}{32}\) by comparing 29 and 21 ? Explain. How can Julie compare her scores?. Answer: Divide the number of correct answers to the number of alt questions on both tests (round to 3 decimal digits). Compare those decimaL numbers to see on which test she scored better 21 ÷ 23 = 0.913 29 ÷ 32 = 0.906 0.913 > 0.906 She got a higher score on the first test. You can not compare those fractions by comparing 29 and 21 because the denominators are not equal. You could do that if they were equal.

Question 31. Look for a Pattern Look at the decimal 0.121122111222…. If the pattern continues, is this a repeating decimal? Explain. Answer: It is not a repeating decimal if the pattern continues This is not a repeating pattern. This pattern is created by adding 1 and 2 after 1 and 2 respectively. The pattern of a repeating decimal has to repeat without adding any other decimal in the pattern Example: 0.567567567… = \(0 . \overline{567}\) Is a repeating decimal. 0.56556555655556… IS NOT a repeating decimal because the pattern has an additional 5 at every repetition. This is not a repeating decimal if the pattern continues.
