## Mission Briefing — Counting forward and backward to 100

In this lesson, you practice counting forward and backward between 0 and 100. You use a hundred chart and a number line to see how numbers go in order.

Counting forward (up)

- When you count forward, the numbers get bigger.
- You say: 37, 38, 39, 40, 41, 42…
- On a number line, you move to the right.

Counting backward (down)

- When you count backward, the numbers get smaller.
- You say: 42, 41, 40, 39, 38, 37…
- On a number line, you move to the left.

Hundred chart and tens lines

- A hundred chart shows numbers from 1 to 100 in rows of 10.
- Going across a row, you count forward by ones.
- Going down a column, you jump forward by tens (10, 20, 30, 40…).

When you practice, always say the numbers out loud and point carefully so you do not skip or repeat any number.

## Training Run — Counting on and back with real objects

Tap to play and Pause.

Count a few small objects one by one, touching each as you say the number. Now point to a number like twenty on your chart and count forward, then backward. Take your time and repeat it once more. When you’re ready, open the tracing pad and write one number you counted. Try another number after that. Say each number as you write it.

## Practice 2 — Number line questions

Tap the correct tick on each number line. Watch how the numbers move by ones and tens.

#### Tap the tick that shows 5.

#### On this number line from 0 to 20, tap 10.

#### Tap the tick that shows 27.

#### Tap the tick that shows 33.

#### On this number line, tap the tick for 60.

#### Tap the number that is 10 more than 30.

#### Tap the number that is 10 less than 70.

#### Tap the tick that shows the number just before 100: 99.

## Practice 3 — Slider questions — Count and find numbers

Move each slider to the correct number. Say the numbers out loud as you slide.

#### Move the slider to show a number that is one more than 29.

Current: 0

#### Move the slider to 47. Say the numbers as you count up to it.

Current: 0

#### Move the slider to 99. That is just one less than 100.

Current: 0

#### Move the slider to the number that is one less than 50.

Current: 0

#### Move the slider to 80. Count 10, 20, 30, … as you slide.

Current: 0

#### Move the slider to 5. Start at 0 and count up by ones.

Current: 0

#### Move the slider to 64. It has 6 tens and 4 ones.

Current: 0

## Quick Check

#### What comes after 60 when you count by tens?

61 70 80

#### 47 has…

4 tens and 7 ones 7 tens and 4 ones 47 tens

#### The number just before 100 is…

90 98 99

#### What comes after 34 when you count by ones?

36 35 44

#### Ten ones make…

one ten one hundred one thousand

#### 30 is…

2 tens and 10 ones 3 tens 3 ones

#### Which list shows counting by tens?

1, 2, 3, 4, 5 10, 20, 30, 40, 50 11, 22, 33, 44, 55
