Ok here's my ideas so far, please read them and give me feedback (Good or bad -all is welcome!) Am not sure if i'm over complicating things. Firstly to explain the concept we will look at socks! So i'll ask a child to the front and ask how many socks they've got on, and write it on the board. Then i'll ask the class to guess how many socks we will have if i invite another child to the front, then we'll try it and see and count. Then i'll say that two and two makes four and explain that two doubled = four. Then invite another two children up and tell them that this time we'll have double the number of children (Two lots of four socks!) What will be the answer? and then probably pause there. Then i'll put up a coat hanger, and count on three pegs (With socks pegged on) and say that i need to double the number of socks - how many more pegs am i going to put on to the coat hanger to double it? and hope the answer will be three, then ask them to work with a thinking partner to double three to work out how many pegs altogether. Am i over complicating? After that we'll go into independent work which i haven't thought of yet!
