YUMMY food for Passover

Passover will begin this year at sundown on Monday, April 10th. Jewish families will gather to commemorate the exodus of the Children of Israel from slavery in Egypt. The celebration begins with a traditional meal, the Seder, where the story of Exodus is retold and special foods are eaten to remember that long ago passage.

We have two activities that involve traditional Passover foods.

Coconut and chocolate chip macaroons
Two activities:
  • Halving, quartering, and three-fourthing recipe.
  • Creating a general rule for doubling, halving, or whatever...ing the recipe.
    CCSS: 5.NF, 6.NS, 7.NS, 7.EE, MP7 , MP8

  • Mom's matzo ball soup
    Tripling fractions, adjusting proportions, and maintaining the ratios to create one humongous matzo ball.
    CCSS: 5.NF, 6.NS, 7.NS, 7.EE, MP7 , MP8

    What does 95% confidence in the poll results mean?

    There were polls about who would win the Presidential election. Now there are polls about approval ratings for Congress and President Trump.  You can see the latest poll results here.

    I get so confused when polling results are reported.  What is this 95% confidence measure? What's the margin of error?  What is standard deviation?

    In this activity students consider the errors in choosing polling samples, find the absolute mean data difference, the standard deviation of a sample and calculate the margins of error.

    Pascal coloring and modular math

    Pascal'sImagesThis is the third and final activity in the Pascal's Triangle series.  In this activity students again have the opportunity to color as they investigate Pascal's triangle and the patterns that it shows.  The activity might be used first in class and then that evening for homework.  Pascal's Triangle is explored for patterns, coloring, and motivation to learn about modular arithmetic or clock math.

    Greatest March Madness program


    Based on this data, which do you think is the greatest March Madness program ever?

    Once students decide their “best program ever” challenge them use a different criteria than they originally used. That is, ask them to think of another way to determine the best program ever.  There are lots of ways to think about it.  No one way is the only way or the correct way.  The point is to get students reasoning and communicating mathematically. 

    Alarming ice cracks on Brunt Ice Sheet in Antarctica

    A new, fast-growing ice crack is forcing the Halley VI British research station in Antarctica (shown above) to be moved.  Fear of a huge break-off from the ice sheet is alarming not just to the scientists on the station but to all of us.  At what rate is this crack growing and how large will this iceberg be when it breaks off?  Click below for the activity:

    CCSS: 6.G.A, 7.G.A, 7.G.B, HSG/GPE.B.7, HSA/CED.A.2, HSG/SRT.A.1, HSN/Q.A.1
