3rd Grade Math Review: Day 12
In yesterday's post we reviewed spent some time looking at perimeter and intervals of time. Today we finish the entire 12-day review with a look at Reporting Category 4 - Data Analysis and Personal Financial Literacy.
Frequency Tables and Dot Plots
Line plots are introduced to students for the first time in 3rd grade. They are a handy way of of examining the distribution of data, an important skill that is built upon in upper elementary. Here's a video showing how to make them.
With that explanation, why not try out this practice problem?
Pictographs and Bar Graphs
Bar graphs are first examined in 1st grade. Now in 3rd grade, however, students really start to look at scaled intervals. Here's a video explaining what that means.
Now you can try your luck with this STAAR released test question.
Solving Data Problems
More than just creating and interpreting different graphs, students are expected to solve one- and two-step problems invovling various graphs. Watch the video below for an explanation.
Here's a practice problem that you can use to test your skill.
This was a griddable response item on the test, so you don't have any multiple choice responses to choose from.
