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.

We started to look at basic concepts in fractions. Problem 11 Share this equally among 4 persons. The class were challenged to find a way where the four equal parts are all different shapes. This is one solution.

Problem 12 is on sharing 3 fourths of a cake equally among three persons.

Problem 5
Based on As I Was Going to St Ives, show how many persons, cats and sacks there are in the rhyme.

Problem 6
This is for two players. Select any number less than 20. Take turns to subtract either 1 or 2. The winner is the player who gets to zero. Think about the strategy to win the game.

Problem 7
Think about different ways to calculate 5 + 7 + 6.

Shareefah shared a video on ten frames on her blog.

Problem 8 Jack & The Beanstalk (My Favourite Video!)
Share 51 golden eggs among three persons.
In how many of these ways do Jack get more than the other two persons (each person gets at least one egg)? What if they are shared equally among three persons?
