Patterns, Clapping Patterns, Addition and Subtraction, Coney, Magnets. Math O 2.0 25 Oct 2015



Clapping
this means 'right left left right'
Blue = Clap, White = no clap
(Too confusing)

Blue = Right hand, White = Left Hand




Lego patterns in sets of 4





Addition and subtraction 

Many variations of:
* Addition
  * We have two blue legos and two white. How many total?
* Subtraction:
  * 6 legos, take away 2, how many are left?
  * Start with 6 legos. Look over there! I hid some legos, how many did I hide?







Buying food

Each kid gets 5 pennies and two nickels.

We have many different items. How many pennies do they cost?

A carrot costs 4c for 1/2. How much is a whole?




Experiment 

Which items are magnetic?
What makes an item magnetic? (remains unanswered, may return to this next time)
