Bikes - November 19, 2012

John loves to ride a Big Wheel (because it has 3 tires). He likes to go to the playground because there is a place just for Big Wheel riders and bicycle riders to use. When he got to the playground, he joined 2 other Big Wheel riders and 3 bicycle riders. How many wheels were on the playground? Show how you know.

Task from Exemplars: www.exemplars.comOne half of the vehicles at Erin's Bike Shop are tricycles. The rest are bicycles. David counted a total of 45 wheels in her shop. How many are bicycles and how many or tricycles? Show your thinking.
