Fast Clapper - 3 Act Math Task - Nathan Kraft

Using Real World Rates and Proportional Reasoning The following 3 act math task shared by Nathan Kraft (@nathankraft1) involves proportional reasoning with opportunities to address learning goals around rates, proportions, rates of change and creating equations. Jon Orr and I have used this task in presentations a number of times over the past few months and many have asked us to share our slide deck and other resources with a summary. So, here we go! Act 1 - Sparking Curiosity Show the following video: https://youtu.be/wT_d2GOEm_0 *Note that this is an edited version of Nathan's video where I have blacked out the number of claps.

Baby Beats - 3 Act Math Task - Rates of Change

Real World Math in Proportional Reasoning The following 3 act math task involves proportional reasoning and rates of change. Act 1 - Setting the Stage Watch the following video with audio of the heartbeat of my baby in the womb. http://youtu.be/KVnBgc6PXvw Suggesting that the students estimate how many beats per 10 seconds, beats per 30 seconds and beats per 1 minute is a good start to having them think about proportional reasoning and rates of change. Act 2 - Giving Information The following video will give students a number of beats per period of time. They can then use this to help them determine the number of beats per minute or any other suggested rate you would like. http://youtu.be/kp1Ei13uOqg Act ...
