EDU330 Elementary Mathematics Session 4 on 26/09/13

Do you see multiplication in this arrangement of lanterns for the Mid Autumn Festival in Chinatown in Singapore?

Problem 13  is based on a 'mind-reading' read. Choose two  digits A and B.
Make a 2-digit number AB and add the numbers A and B to get a sum.
Find the difference between AB and the sum.
If you know A you can figure out what the difference is.

In Problem 14 we explored ways to subtract 3 1/4 - 1/2

In Problem 15, the three little pigs shared 4 pizzas equally.

Problem 16 is to figure out the multiplication facts for 7 by the doubling method, the distributive property and the subtraction method.

Problem 17
Draw a polygon on geoboard paper. How many times is it as large as the square?
Jessica shares her solutions at her blog.
