Explain to students that when we talk about halving – we are talking about putting a group of items into two groups. Provide each student with a mini whiteboard and pen. Give students a halving story for them to answer. If students need they can draw a picture to help them answer the question.

Now ask the students to write a halving story problem. Ask them to share their problem with a friend and have their friend solve it. Discuss the outcome with students: if an uneven number was being halved. Discuss halving a unit of one and explain that we write half of a unit as .5.
