Harvesting

On a farm, there is lots of work to do.

One of the tasks is harvesting. Harvesting means to pick or gather the items that you grow.

Examine the following images. What do you notice? What do you wonder?

In the images, what items are being harvested?

Count the number of each item harvested.

Action

Who harvested more?

Farmer A and Farmer B have been busy harvesting on their farm!

First, they harvested corn.

Examine the following image.

20 cobs of corn arranged in groups of 5 with a label underneath that says Farmer A: 20 cobs of corn. Next to it is 25 cobs of corn arranged in groups of 5 with a label underneath that says Farmer B: 25 cobs of corn.

Who harvested more?

Select the correct answer, then press “Check Answer” to see how you did.

How do we know who harvested more?

Let’s learn!

When we count, we usually count from smallest to largest.

Count along:

As we count, the numbers get larger.

Your turn!

Next, let’s compare the apples harvested by Farmer A and Farmer B.

  • Farmer A harvested 48 apples
  • Farmer B harvested 32 apples

Let's explore a Hundreds Chart! Try using it yourself and ask for help if you need it! Place an apple on the numbers 48 and 32.

Which number is larger: 48 or 32?

Press ‘Answer’ to learn which number is larger.

48 comes after 32, so 48 is larger.

A hundreds chart with numbers from 1 to 100. There is an apple sticker placed on number 32 and number 48.

Ordering numbers

Farmer A collected 3 baskets of eggs from the chickens on the farm.

3 wire baskets in a row with eggs. First basket: 21 eggs with a label underneath that says 21 eggs. Second basket: 15 eggs with a label underneath that says 15 eggs. Third basket: 26 eggs with a label underneath that says 26 eggs.

Let’s use a Number Line to put the numbers in order from smallest to largest!

A Number Line is a tool we can use for counting and comparing numbers.

Examine the following Number Line. The dots tell us the number of eggs in each basket.

A number line from 1 to 30 that shows all numbers. There is a dot on the number line at number 15, number 21, and number 26.

From smallest to largest, the numbers are: 15, 21, 26

Try It

Your turn!

Farmer B harvested cherries from 3 different trees:

  • First tree: 42 cherries
  • Second tree: 48 cherries
  • Third tree: 36 cherries

Can you put the numbers in order from smallest to largest?

Consolidation

At the market

The farmers are going to sell some of the items that they harvested at a market.

Let’s compare the cost of the different items.

Hint: to help you with the following tasks, you may choose to use a Number Line or a Hundreds Chart to show your thinking.

Let’s compare: Task 1

Here are the first items for sale:

a quart of apples with a label underneath that says Apples $8. Next to it is a carton of a dozen eggs with a label underneath that says Eggs $6.

Which item costs more, the apples or the eggs?

Let’s compare: Task 2

Now, let’s compare the next items for sale:

A head of lettuce with a label underneath that says Lettuce $3. Next to it is a small basket of potatoes with a label underneath that says Potatoes $4.

Which item costs more, the lettuce or the potatoes?

Record your thinking using a method of your choice.

Examine all the items at once:

A collage of four items. The first item is a quart of apples with a label underneath that says Apples $8. The second item is an open carton of a dozen eggs with a label underneath that says Eggs $6. The third item is a head of lettuce with a label underneath that says Lettuce $3. A small basket of potatoes with a label underneath that says Potatoes $4.
