Place value division with base ten blocks

How many rods do I need to draw in the tens place? (Hint: One ten equals one rod?)

• 20

• 5

• 2

• 25

How many units do I need to draw in the ones place?

• 20

• 0

• 5

• 2

We represent 25 as 2 rods and 5 units.

What is our next step?

• Write 25 in word form.

• Add 25 + 5.

• See if we can make a group of 5 from the tens.

Can we make groups of 5 from our tens?

• Yes

• No

We have 2 rods, not enough for a group. So we turn the tens into ones! How many ones do we get from 2 groups of 10?

• 10

• 2

• 20

The value of 2 groups of ten is 20! So 2 rods become 20 units.

How many groups of 5 do we have now?

• 25

• 5

• 4

We got 5 groups of 5!
That means:

 $25\div5=5$  

What is the OPPOSITE function of division that we can use to check our answer?

• Subtraction

• Addition

• Multiplication

Here we have 524 - 5 flats, 2 rods, and 4 units.

Use a paper and pencil to solve!

How many groups of hundreds did you circle?

• 1

• 5

• 2

We circled one group of 4 flats. We have 1 left over, and break it down into 10 rods.

How many groups can we circle in our tens place now?

• 3

• 12

• 0

We made three groups in the tens place with none left over! Now how many groups can we make in the ones place?

• 0

• 4

• 1
