Can a landmark settle it?
Decide when benchmark evidence determines an ordering.
Explore this lesson →9 practice questions · Optional read aloud · Thinking pad
Let’s understand the idea.
- Locate each fraction relative to the chosen benchmark.
- Opposite sides or an endpoint may settle the order.
- Being on the same strict side leaves this argument unfinished; choose more evidence.
Something to notice
Ask the learner to show two different possible orders for amounts above one half, then choose a useful next argument.
Try it. Change it. Explain it.
Open the lesson to use its pictures and controls. In How it works, connect the picture to the idea. In Play & discover, change the quantities and notice what stays the same. In Your turn, answer questions and use the explanation to check your reasoning.
You can ask for help, draw on the thinking pad, or listen to the question and answer options. Progress distinguishes independent work from work completed with help.
