Monday: Timers and Minutes

Ferris the Fox sets a little kitchen timer on the counter. It ticks softly.

Bennie the Bear reads a recipe card. "It says cook for 30 minutes," he says.

"What do you notice about the timer?" Ferris asks. "How does it help a cook?"

Riley the Raccoon taps the buttons. "Here is a hint," he says. "Count the minutes, not the ticks."

Why cooks use timers

A recipe often says how many minutes something takes.

A timer counts those minutes for you. It rings when the time is up.

Then nobody has to guess, and nobody forgets.

Setting the timer is a great kid job.

Safety first
A grown-up handles the oven and the stove.
You set the timer and tell the grown-up when it rings.

Elapsed time: how long?

Elapsed time is how much time passes from the start to the end.

Start at 4:10. Set the timer for 20 minutes. It rings at 4:30.

A number line helps. Jump from the start time by 5 or 10 minutes.
