Core concept: Different lengths can be measured by using comparisons.
We can create half a length by dividing objects into 2 equal parts.
Learning Intention:

Students are learning that:
Students are learning that:
- length can be compared by aligning the ends and described using comparative language
- the length of a piece of string remains unchanged whether placed in a straight line or a curve.
- when a length has been divided into 2 equal parts, the parts are called halves
- the position lengths have been divided into can be described as about halfway, more than halfway or less than halfway.

Students can:
Students can:
- compare and describe length using language such as longer than, shorter than, the same as
- explain why the length of a piece of string placed in a straight line is the same as a curve.
- divide a length into halves
- describe positions as about halfway, more than halfway or less than halfway.

Explain to students that you are going to throw a collection of pebbles onto the ground. Ask students to find the total by instantly recognising (subitising) or counting with one-to-one correspondence.
As a class, ask students to count the collection of pebbles aloud, pointing to each pebble to support counting with one-to-one correspondence.
Ask students to show a corresponding finger pattern.
A student is then selected to put the pebbles into the layout of a dice dot pattern. Check the layout of the dice pattern created using a large dice

Model using comparative language to describe the length of the sunflowers drawn, for example, this sunflower is longer than the stick.

Have students cut a piece of string the same length as the stick.
Encourage students to wrap, move and shake the string like a snake and again compare with their drawing to reinforce that the string remains the same length.
Ask students to consider if they created a curved stem for their flower instead of a straight stem would they be the same length.
Provide time for students to make a cucumber, carrot, and banana from modelling clay (see Figure 16). Use a craft stick to cut the fruits and vegetables and describe the position lengths have been divided into, for example, about halfway, more than halfway or less than halfway.
