This problem solving activity has a measurement focus.
Niko makes a train from three different coloured rods.
Kaia does too.
Niko's train is longer than Kaia's.
What coloured rods might each person have used?
This is an opportunity for the students to compare lengths. It can be done by calculation if students know the "value" of the Cuisenaire rods or by using the rods and comparing the lengths. Prior to beginning this unit, your students should have some experience with exploring number values with Cuisenaire rods.
Niko makes a train from three different coloured rods.
Kaia does too.
Niko's train is longer than Kaia's.
What coloured rods might each person have used?
Kaia's train is twice as long as Niko's. What coloured rods might each person have used? Incorporate fraction language (e.g. half, double).
There are many possibilities. Have students refer to their recording and take turns to demonstrate their findings to the group/class.
Have students demonstrate their findings by showing that two of Niko's trains can fit alongside Kaia's train.
If students know, and have used number values, listen for the language of half and double as they demonstrate their findings.
