Lesson 198 SWBAT combine partial quotients and find

Lesson 198 SWBAT combine partial quotients and find an alternate way to get the total quotient.

Today we are going to start with a problem. You will have a few minutes to work and then we’ll share out all our ideas.

How did you represent Samantha’s Samantha had 40 red tiles that tiles? What equations did you write? she put into 4 rows. She also had 28 red tiles that she put into 4 rows. Draw a picture of what Samantha did. Write as many equations as you can to represent the array that Samantha made.

Lesson 199 SWBAT represent the partial quotient method with the area model on grid paper.

Dan had 56 square tiles that he wants to put into 4 rows. How can Jason arrange his tiles? How many tiles will be in each row?

Lesson 200 SWBAT represent the partial quotient method with the area model (not on grid paper).

Today we are going to keep using arrays to do the partial quotient method except we won’t have grids to help us. We still want to show our work with the area model and equations.

Josie has a garden with an area of 75 square feet. The width of the garden is 3 square feet. She is going to split her garden into three different rectangles for carrots, peas and lettuce? . What dimensions could Josie use for each section of her garden?

Lesson 201 SWBAT interpret the meaning of quotients in the context of a story.

We have been working on division. There are two different types of division stories. • To make sense of these problems, let’s brainstorm different types of groups and things in each group.

Let’s create stories with one of the examples we thought of.

Now let’s think about a problem that’s already written. What kind of problem is it? What words will we put after our answer. Jasmine has 10 cupcakes. She wants to put 2 cupcakes in a box to sell at the school bake sale. How many boxes can she make?

Now let’s think about a problem that’s already written. What kind of problem is it? What words will we put after our answer. Rudy had a rope that was 10 inches long. He wanted to cut it into 2 pieces. How long will each piece be?

Now we will do this work with the bigger numbers we’ve been working with all week.

Lesson 202 SWBAT solve story problems with division.

Today is just a work day. We are going to solve all kinds of different types of division problems. Some of them will be two step division problems. Your job is to make sure to show careful work and to label your work with the correct words.

Lesson 203 SWBAT explain how they found a quotient in words.

Today we are going to focus on explaining how we get our answer in words. What kind of language do you think we will use? •

Lesson 204 SWBAT correct someone else’s reasoning in finding a quotient with partial products.

Today we are going to work on correcting other people’s work. What are the steps that we use for that?

Sometimes the work that we will see might look different than we are used to. We still should follow their strategy and see if we can make sense of it.
