Valentine's Candy Graph - Section 3: Independent Practice

Note the error made as the student was adding data to the category columns. I failed to point out ahead of time that the labels at the bottom are not part of the data count. They are labels for each column to know where to place each colored candy heart. This was a good opportunity for me to go back and point out to my students that it is important to build their graph correctly or there will be errors when trying to answer questions pertaining to the graph. This graph was not already numbered along the side, but future graphs may be, so it is necessary that they learn now to structure their data correctly.

# Valentine's Candy Graph

Lesson 6 of 9

## Objective: SWBAT use a bar graph to answer questions about the total and how many more/less in each category.

## Big Idea: First graders need to be able to organize and interpret data. I am taking advantage of our holiday party and encouraging my students to graph their candy hearts and decipher their results.

*30 minutes*

#### Rev Them Up

*5 min*

We are using Valentine Heart Candy for today's lesson. We will begin our lesson by counting handfuls of hearts. I will walk around and give everyone a handful of candy hearts and ask them to count how many they have.

I say: *Students, we will be using our candy heart in our math lesson today. Count how many hearts you have on your desk and then tidy your desk up so that you are ready for our lesson.*

#### Whole Group Interaction

*10 min*

My goal today is to have students look at their graphs and practice identifying the total along with how many more or less are on in each category on their graph (1.MD.C.4). I want them to be careful and think strategically towards identifying answers. They are constructing a real math model to analyze and make conclusions from. They will be using this graph information, reviewing the data, and interpreting the results (MP4). It is not enough to just guess at an answer, but they must study the graph and compare/contrast columns to identify results.

I will have my students use the candy heart bar graph available here. I will have them use the handful of candy hearts I gave them to design a bar graph. They will place their heart candy into each correct category.

Of course they will want to know if they can eat the candy, and I will let them know when we are finished with our lesson, they can eat the candy.

#### Independent Practice

*10 min*

I will pass out the Valentine worksheet for my students to analyze the results on their candy heart bar graphs. The questions on this worksheet will be a challenge and spur my students to use larger numbers. I designed questions to have them not only look at their own graph results but also the results of their group members, which will require them to collaborate in their groups and develop their precise math talk. I will have them complete the first box of questions on their own, then I will have them do the second box's questions one at a time with me. I want to make sure they understand what those complex questions are asking.

You can see how some of the lesson went here as we discuss how many altogether.

#### Lesson Closure

*5 min*

I will have my students gather together at the carpet and we will discuss our results. I will ask students to share how many they had of some colored hearts and talk about why we had different results.

Also, I will ask the following questions to extend their thinking:

*What should we do if a question ask us how many altogether for the whole group?**What was our data for this graph?**What does least and greatest mean?*
