This estimation jar is one of my new favorites to use with my kiddos! It teaches students how to find percents and gives them a tool to VISUALIZE and take ownership as to what percents REALLY mean. The kids liked it so much we did it again the LAST WEEK of school because of their interest! ☺ The Estimation Jar can be used over and over with your students in the same school year.
Complete with photographs, the teacher pages explain how to use the jar in your classroom.
In the Estimation Jar Activity students convert fractions into decimals and then percents. Students will graph their estimates on line, bar, and pie graphs. They will then be given the opportunity to explore what these graphs REALLY mean and reason which graphs best show their estimates.
Also included with this activity are mock surveys, where students look at graphs already made and reason which is the best way to show the information.
Lastly, students can also conduct a survey of their own for more practice with finding percentages.
It really is a fun way to learn (and teach) percents! :)
Common Core and Smarter Balanced Aligned
Two of the Four Smarter Balanced math claims have been incorporated into the activities:
Smarter Balanced Claim #3 – Communicating Reasoning
“Students can clearly and precisely construct viable arguments to support their own reasoning and to critique the reasoning of others.”
Smarter Balanced Claim #4 – Modeling and Data Analysis
“Students can analyze complex, real-world scenarios and can construct and use mathematical models to interpret and solve problems.”
