CCSSM Standards

CCSS.MATH.CONTENT.3.MD.B.3
Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one- and two-step "how many more" and "how many less" problems using the information presented in scaled bar graphs. For example, draw a bar graph in which each square in the bar graph might represent 5 pets.

CCSS.MATH.CONTENT.3.MD.B.4
Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show the data by making a line plot, where the horizontal scale is marked off in appropriate units— whole numbers, halves, or quarters.

Standards for Mathematical Practice

1.  Students should be able to check their work by backtracking and reviewing the graph based on the original collected information

2. Since the graph will typically be visually expressed with minimal numeric expressions it will both bring meaning and give student flexibility on how they wish to create and use their bar graphs.

3. Using visual manipulatives and the data collected students will be able to determine the graphs credibility

4. Students will be able to show the relationships in the graph to identify mathematical conclusions such as addition, multiplication etc.

5. Appropriate tools such as visual aids when graphing (can be done with colors as well) and manipulatives can be used to deepen the students understanding of the problem/lesson

6. Clear definitions will be discussed within the students own reasoning

7. Patterns and structure will be discerned

8. Students will notice that if calculations are repeated general methods and shortcuts can be created such as increasing the y-axis amount when charting quantities

Summary

  A group of kids runs a lemonade stand in order to save enough money to for repairs to their clubhouse that is falling apart. They make a bar graph in order to track their lemonade sales and track which days generate the most income in order to adjust their profit intake.

Rating- ⭐️⭐️⭐️

 This book is engaging for children and uses real-world concepts and situations in order to bring across a mathematical subject that might otherwise be lost on kids or a detached subject. Lessons for this topic in the book can be adjusted based on a child’s grade level, which is important and practical for teachers.

Classroom Ideas

This book can be used to teach the mathematical concepts of representing and interpreting data through the use of addition, subtraction, multiplication, patterns, and sequences with possible visual aids.

  Read the story with students and describe what’s happening as it’s being told in regards to the illustrations. Talk about the graphs and how it presents in the story. Questions will be asked and answer during the story such as, “on which day was the most cups of lemonade sold?” etc. and “what facts do you think could have affected the sales?”.

   Making graphs based on what’s found in the classroom, debating the various ways that the x-axis should be represented (5’s, 10’s etc.). This would help students exercise how there are various ways to create graphs and adjust graphs in order to reflect individual use.

    Setting up one's own lemonade stand or keeping track of what happens in the students daily lives (dog being walked, how many cars outside, amount of trips to the bathroom in a day etc.) and creating a graph to keep track (through days or hours) showing the amounts through visual representation on the graph. This would help students see how graphing can double in expressing everyday activities.
