Unlock the Problem
Sean and his crew operate a fishing charter company. They caught a blue marlin and amberjack. The weight of the blue marlin was 12 times as great as the weight of the amberjack. The combined weight of both fish was 1,014 pounds. How much did each fish weigh?
What do I need to find? I need to find the weight of each fish.
What information am I given?
I know that they caught a total of 1,014 pounds of fish and the weight of the blue marlin was 12 times as great as the weight of the amberjack.
I can use the strategy of Addition and Substitution and then divide. I can draw and use a strip diagram to write the division problem that helps me find the weight of each fish.

Jason, Murray, and Dana went fishing. Dana caught red snapper. Jason caught a tuna with a weight 3 times as great as the weight of the red snapper. Murray caught a sailfish with a weight 12 times as great as the weight of the red snapper. If the combined weight of the three fish was 208 pounds, how much did the tuna weigh?
What do I need to find? Answer: I need to find the weight of tuna
What information am I given? Answer: I know that Jason, Murray, and Dana went fishing. Dana caught red snapper. Jason caught a tuna with a weight 3 times as great as the weight of the red snapper. Murray caught a sailfish with a weight 12 times as great as the weight of the red snapper and the combined weight of the three fish was 208 pounds
What is my plan or strategy? Answer: I can use the strategy of Addition and Substitution and then divide
Solve It is given that Jason, Murray, and Dana went fishing. Dana caught red snapper. Jason caught a tuna with a weight 3 times as great as the weight of the red snapper. Murray caught a sailfish with a weight 12 times as great as the weight of the red snapper and the combined weight of the three fish was 208 pounds Now, Let the weight of the red snapper be: x Pounds So, The weight of the fish caught by Dana = x Pounds The weight of the tuna caught by Jason = 3x Pounds The weight of the saltfish caught by Murray = 12x Pounds Now, According to the combined information, x + 3x + 12x = 208 Pounds 16x = 208 x = \(\frac{208}{16}\) = 13 Pounds So, The weight of the tuna caught by Jason = 3x = 3 × 13 = 39 Pounds So, The tuna weighed 39 pounds.
How can you check if your answer is correct? Answer: Substitute the weight of the tuna in the total weight of the three fishes and check whether the answer is equal to the combined weight of the fishes caught by Dana and Murray

Texas Go Math Grade 5 Lesson 2.8 Homework and Practice Answer Key
Eddie’s Moving Company moved 3 boxes out of Mrs. Diaz’s house. The box labeled “Kitchen” was 4 times heavier than the box labeled “Bedroom.” The box labeled “Library” was 14 times heavier than the box marked “Bedroom.” If the combined weight of the boxes was 817 pounds, how much did the box labeled “Kitchen” weigh?
Question 1. What do I need to find? Answer: I need to find the weight of the box labeled “Kitchen”
Question 2. What information am I given? Answer: I know that Eddie’s Moving Company moved 3 boxes out of Mrs. Diaz’s house. The box labeled “Kitchen” was 4 times heavier than the box labeled “Bedroom.” The box labeled “Library” was 14 times heavier than the box marked “Bedroom” and the combined weight of the boxes was 817 pounds
Question 4. Solve. Let the weight of the box labeled “Bedroom” be: x Pounds So, x + 4x + 14x = 817 Pounds 19x = 817 So, 817 ÷ 19 = 43 So, I can multiply 4 by 43 to find the weight of the “Kitchen” box. So, The box labeled “Kitchen” weighed 172 pounds.
Question 5. An athlete ran 1,200 laps around a track over a two-month period. He ran 4 times the number of laps in the second month than he ran in the first month. How many laps did the athlete run the first month? Answer: It is given that An athlete ran 1,200 laps around a track over a two-month period. He ran 4 times the number of laps in the second month than he ran in the first month Now, Let the number of laps run by an athlete in the first month be: x laps So, The number of laps run by an athlete in the first month be: 4x laps Now, According to the given information, x + 4x = 1,200 5x = 1,200 x = \(\frac{1,200}{5}\) x = 240 laps Hence, from the above, We can conclude that The number of laps did the athlete run in the first month is: 240 laps

How to Use a Math Medic Answer Key
Updated: Aug 7
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 in the margins.
QuickNotes: The teacher provides a few key summary statements from the activity in the QuickNotes box - making 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 its 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:
Activity (blue), Debrief Activity (red), QuickNotes (red), Check Your Understanding (blue)
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.
