Introduction

Objective: I can solve one and two step compare problems using data represented in scaled bar graphs.

Resources:

1.  Solving problems using bar graphs

 

2. Using data to solve problems

 3. Go Math page 119

 4. How to make a Bar Graph?

5. How to create models for word problems.

6. Quick: Parts of a Bar Graph. 

Task

Task:

 

Use the data in the tally chart to make a bar graph. Then, answer the questions. For each question be sure to:

 

  1. Write the number sentence that helped you solve and draw a model drawing that helps you solve.
  2. Identify the key words in the problem and what operations those words let you know to do.
  3. Describe the steps you took to solve the problem.

Questions:

  1.  Andrew's favorite food is the food that has 5 fewer votes than red. Which food is this?
  2. How many more students liked pizza and burgers combined than hotdogs?
  3. How many students voted in all?
  4. What would the bar graph look like if there were another category called "fries" and a total of 50 students voted?

 

Process

Divide your paper into four sections like below. In each section answer ONE question. Make sure you include the 3 important elements of your response.

Success Criteria

Check your work to make sure you have each of these items:

  • I wrote a number sentence for each problem.
  • I created a model drawing for each problem.
  • I identified the key words in each problem.
  • I described which operation I needed to do, and HOW I know.
  • I described the steps I took to solve the problem (using sequence words like first, next, and last).
  • I made choices that helped me grow as a learner.
  • I used the information tools available to guide and extend my inquiry.
