Hinweis der Redaktion
- I’ll start every class with a book- one you are welcome to use, but not in assignments B or C! Why? To show you how to connect what you already do to math & science. Each book I’ve chosen melds with the units we are studying that day. Why this book? Unit 31 geometry http://www.jmeacham.com/images/math/sir.circumference.and.the.dragon.ofpi.jpg
- First, simple comparing of the numbers, 28 < 36 Then graphing them together onto bar graph – visually seeing what is greatest
- Same information, show in a different style of graph- “line graphs demand concrete operational thinking because more than one aspect of the data must be focused on at the same time”. Pg 422 For a child to make this they have to connect one day’s data to the next, which means tracking another layer than before.
- Number line –No matter where we start, 2 or 3, we get to the same solution = 5. Write your own and draw a number line to show that it works
- Great visual way to show children that subtraction is not commutative.
