Grow Beasts: Growing understanding through active engagement and inquiry 2012 National Council of Teachers of Mathematics Annual Conference April 26, Philadelphia, PA Mark Roddy, Ph.D. Seattle University
Objectives: Students engage in: an application of data gathering, prediction, slope, linear (and non- linear) rates of change; the use of inquiry and student choice to engage in the construction of understanding and skill; the development of positive disposition in mathematics / science. Grow Beasts: Growing understanding through active engagement and inquiry
How does a Grow Beast grow? Let’s take a look, shall we?look Kinesthetic -> Tabular -> Graphical -> Abstract (After AIMS “Model of Learning” )
Using Grow Beasts to teach math In a second grade class – measurement, data recording, prediction and estimation; In middle school – ratio, proportion, rate and slope; In high school – Inquiry, modeling, research, presentation, etc. WSMC WSMC
How does your Grow Beast grow?
Simulated Grow Beasts
Grow Beasts A, B and C
Here are your three GBs: “A” was grown in a medium salt solution (10cc/200ml) “B” was grown in warm water (~30 o C) “C” was grown in room temperature water (~20 o C) HOURS elapsed Med SaltWarm WaterJust Water begin 10AM 10/8/08 10cc/200ml30 degrees C20 degrees C ABC Grow Beasts: salt water, warm water, and just water CAB Tabular

To 500 ml of room temperature water I will add: somewhere between 5 and 50 cc of salt, or somewhere between 5 and 50 ml of lemon juice. Your team’s mission is to mathematical develop a mathematical model model that will enable you to accurately predict the length of the GB at 6-hour intervals for four days.

Using Grow Beasts to Teach Math 5 th grade: measurement 6 th grade: ratio and rate 7 th grade: rates of change, slope and linear equations 8 th grade: more linear functions and the analysis and summary of data sets
Height vs stride This is an example of middle-level students exploring, exercising choice and making use of the spreadsheet, having had the kinesthetic, the tabular and so forth….
