Grade 3 Math TEKS 3.8B:Solving Data Problems

Learning Target: I can solve one- and two-step problems using the data in a bar graph.

Focuses On:

• Adding values in a bar graph
• Subtracting values in a bar graph
• Solving two step word problems involving addition and subtraction of data in a bar graph

Builds On:

2.10B:

Organize a collection of data with up to four categories using pictographs and bar graphs with intervals of one or more.

1.8A:

Collect, sort, and organize data in up to three categories using models/representations such as tally marks or T‐charts.

1.8B:

Use data to create picture and bar‐type graphs.

Next Level:

4.9B:

Solve one- and two-step problems using data in whole number, decimal, and fraction form in a frequency table, dot plot, or stem-and-leaf plot.

The lesson is designed to support student understanding of the information given in a bar graph. It requires students to solve one and two step addition and subtraction word problems using the data in a bar graph.

The lesson starts by having students solve simple addition and subtraction problems by determining the value represented by the data in the bar graph. The lesson progresses in difficulty as students are asked to solve two step problems involving both addition and subtraction of the values shown in the bar graph.

This lesson can be taught at the same time as 3.8A, which involves representing data in bar graph. It should be taught after 3.4A and 3.4K.

Learning Target: I can solve one- and two-step problems using data from a dot plot.

Focuses On:

• Adding values in a dot plot
• Subtracting values in a dot plot
• Solving two step word problems involving addition and subtraction of data in a dot plot

Learning Target: I can solve one- and two-step problems by interpreting data in a pictograph with a key and scaled symbols.​

Focuses On:

• Interpreting single data points in a pictograph
• Answering word problems requiring addition (combining) or subtraction (comparing) of data in a pictograph

The lesson is designed to support student understanding of the information given in a pictograph. It will require students to not only identify the values given in the graph, but also to add or subtract more than one value.

The lesson starts by having students simply identify the value of one given data point on the graph. It progresses in difficulty as students then find the values of at least 2 data points and add those points together to solve a word problem. It finally requires students to complete this same process for subtraction.

This lesson can be taught at the same time as 3.8A, which involves representing data in pictographs. It should be taught after 3.4A and 3.4K.
