Sensational Smoothies: Metric (Day 2) - Section 4: Closure

Much of the first half of my school year has been establishing a safe, and orderly environment. I have a diverse bunch of learners this year that require me to be very much a "mom" before a "teacher".

I believe that I must show my students the respect that I expect them to also show me. I have seen my students grow leaps and bounds emotionally and then academically. My students need to know that I will provide them with unique learning opportunities, times to be silly, and respect their differences in how they solve problems, the amount of work I give, and so on. I differentiate instruction and tasks by carefully pairing up students, cold calling, think pair share opportunities, and choice boards in which students choose a predetermined number of opportunities based on a larger set.

# Sensational Smoothies: Metric (Day 2)

Lesson 10 of 16

## Objective: SWBAT convert grams to kilograms, & solve multi-step, real world problems.

#### Warm-up

*10 min*

We use Flocabulary's Song The Metric System to review. This site provides a rap style song that my students love, and really get into, and love singing along to. So long as they don't get carried away, I allow them "get down" with it too, and use motions because that helps trigger memory. (I don't specifically tell them what moves.) I let my students listen to the song one time, and then sing along as I play it a second time . Throughout the week, I put this video on during some transitional times for extra practice too. Most of the songs on here are incredibly catchy, and students sing the songs to themselves long after they've heard them. The site provides the lyrics, a quiz, and extension activities. Each song is linked to CCSS too. This song is free, but most of the site is a subscription. I have students listen only the first time, and then then can sing along the second time they hear the song. Sometimes I throw in one of the songs I've used during a transitional time in the classroom.

#### Guided Practice

*15 min*

**Amy is making smoothies. She uses 1.2 kilograms of apples and 600 grams of strawberries. How many kilograms of fruit does Amy use in all?**

I first set my expectations for the students by telling them that today, tomorrow, and the day-after tomorrow they will use these steps. By modeling this I am creating connections so that students will recognize that there is a pattern to problem solving, and it's a procedure to follow. (There's not just a quick answer.) I'm trying to build up their endurance and patience in problem solving.

*A kilogram is _______, so you need to _______.*

*A) Convert 600 grams of strawberries to kilograms.*

*1 kilogram = 1000 grams*

*A kilogram is _____ than a gram, so you need to _______.*

*_______ _____ 1000 = _______*

*600 grams = ________ kilograms*

*B) Add kilograms of apples to kilograms of strawberries. *

*1.2 kilograms + _______ kilograms = ______ kilograms*

*C) Amy uses _______ kilograms of fruit in all.*

We list the givens of the problem, and circle them on the board. Using cold calling, I use student input to lead us through the explanation. By modeling this, I hope that students will use this step-by-step strategy in their future problems.

#### Independent Practice

*15 min*

**Now, you want to determine how many grams of fruit are used, instead of kilograms. How could you do this?**

Using MP1, students make sense of problems and persevere in solving them. Students determine an approach to a conversion problem.

Using MP2, students reason abstractly and quantitatively. Students make sense of the quantities in a problem and the relationship among metric units to solve a problem.

At first my students groaned, as they initially thought that this was going to be quite difficult. Allowing them to work with their table partner, they quickly realized this was pretty simple. You can convert 1.2 kg of apples to grams. You can then add the grams of apples to grams of strawberries.

In the video, you'll hear two students working through this that explain that "it's actually easy", and you'll hear the sentence frame that we used in the Guided Practice that leads the conversation.

This was definitely a teachable moment which built up their math "endurance". Often times, my students give up on a problem if it requires more than one step.

#### Closure

*10 min*

As a class, we connect Math to cooking. We collaborate to write a cake recipe using random ingredients, measured in grams. While the objective is serious, the ingredients can be zany! For example, 400 grams of chewing gum.

As the students call out ingredients, I write them on the board with the given amount. Next, students work with their table partners to convert the amount into milligrams. I know that my students love being silly, especially with MadLibs, so I knew that my students would love making up silly ingredients.
