More on forced choice

Forced choice can also be used to help children achieve success.
One trick with using force choice questions is using what you know they know to help them give the right answer. Everyone likes to be right.
For example if you know that Jamie knows what a banana is

but you are not sure she knows what a pear is. If you ask “what is this? (pear)” and she looks at you blankly try asking “is this a banana or a pear?” She knows it is not a banana so she is more likely to say pear.
If you think she might need extra support you may like to shake your head as you say banana and nod and smile as you say pear. That increases the likelyhood she will get it right and gives you the opportunity to praise her knowledge and keep her engaged in the activity.  
By learning to use forced choice questions to support your child you can help them to give the correct answer. That gives you an opportunity to give them lots of praise.

Using force choices for learning colours
When working on colours start with one eg red . When the child knows that colour introduce another colour eg blue. Then after showing the child a lot of blue examples you can hold up a blue item and say "is this red or blue?". The child knows it's not red so they are more likely to choose blue.  If the child looks confused you might ask again shaking your head as you say red and nodding as you say blue. They get it right you give them lots of praise. Hey isn't this fun. Gradually as they get more confident you drop the head nodding and shaking.

 I have just used red and blue to make my example easier to follow. Choose a colour the child likes for a first colour and make the next colour  you choose quite different.
