This is a simple and fun way to introduce basic prepositions (on, in, under and by/next to) to kids of different ages.
Start by doing the gesture chant using something small like an eraser on their hand.
Gradually make it more difficult (and fun) by adding more objects or plurals. Each time build on the sentence.
Its on my hand.
They are on my hand
Then make a tower out of objects you can find in the classroom and challenge the students to get the objects into the correct area.
You could set a timer to see who can get the most, for example, in the bowl. Make sure they say the sentence each time they throw.
