Note: This is a remake of our 2014 and 2017 activities “How Much Does a Lego Cost?”. How much could the Roman Colosseum Lego set cost ? Student first make a guess and then think about what information would be…
How should I cook my turkey? – Students judge timing, cost, tastiness, and quantity necessary as they plan for the feast. 4.MD.1, 5.NBT.7, 4.MD2, 6.RP.3, 6.NS.3, 7.NS.3 Great video on a deep frying fire with William Shatner. Lots of Cranberries – (new) In this…
When shopping next Friday, students will be able to add some understanding and analysis to the trip after calculating savings in dollars and percents with this timely investigation.
In this timely activity, students learn about how cranberries are grown and harvested; estimate their size and quantities; and see what they can deduce from published statistics.
Here are two very different maps about where Veterans live in the U.S. and which states have the largest density of Veterans citizens. What do these two maps make you wonder or realize? How can you explain their comparison?
In this activity students see the inverse relationship between number of workers and time to complete the whole job. They graph hyperbolas and consider how long the extreme condition of zero people raking might take to complete the job.
Students surmise what the difficulty of a jig saw puzzle entails and use rate calculations to estimate finishing times. They try to confirm whether doubling the number of pieces really increases puzzle completion time by a multiple of four.
Fourteen activities that will please and intrigue your students as October comes to an end.
We found big mixed bags of candy at really good prices … we think. Students are asked to decide which would be the best deal and the worst deal on candy. They can also create their own mixed bags. This activity…
After showing the video consider asking your students what the grouping of students must have been for “colored pencils” to win the class electoral college? Is there more than one possibility? What is the minimum number of students that could have voted for colored pencils for them to still win the Electoral College. Students then consider scenarios where a candidate wins the popular vote, but loses the Electoral College.
The winner of the Presidential Popular vote (November 3, 2020) is not always the same as the winner of the Electoral College vote (January 6, 2021). In this activity students ponder how that could happen … with data. Electoral-college-compare2020.pdf
Use our current data on Halloween spending in America to engage your students in an analysis of the ratios and percents of population, participation, and money spent in honor of October 31st. This activity takes kids through finding parts of wholes as well as ratio, percents and proportion problems. Beware: the tasks in this activity involve some large numbers as well as some challenging fraction/ratio/proportion problems.
First, students need to find the surface area that the M&Ms cover in order to approximate how many M&Ms she needs to finish her cake.
When Brian tried to make the cake, he mistakenly added too much peanut butter. Now all the of ingredients will need to be increased by some percent to insure that the cake maintains appropriate ingredient ratios?
Fraction operations might be more interesting when it involves chocolate. Students reason and calculate what is left of these chocolate bars. The bars are the same size but are molded into different number of sections. Yum!
