Give students a number line from 0 to 1 or 0 to 2 and a set of decimal cards.

Use decimals such as:

• 0.2

• 0.45

• 0.7

• 0.95

• 1.3

Set a timer and challenge students to place each decimal in the correct spot before time runs out.

Then ask bonus questions for extra points:

• Which number is closest to 1?

• Which decimal is between 0.4 and 0.6?

• Which decimal is greatest?

To level up the game, use three rounds:

• Round 1: tenths

• Round 2: hundredths

• Round 3: decimals greater than 1

Students love racing the clock while building real decimal number sense.

Teacher Tip: Use this as a warm-up, center activity, or partner challenge.

Number lines are one of my favorite tools when teaching decimals in 4th grade because they build real number sense.

Students solve decimal problems and color sections based on the answers.

Great for practicing:

• comparing decimals

• decimal place value

• adding decimals

• subtracting decimals

Students stay engaged because it feels like a puzzle instead of a worksheet.

Teacher Tip: Perfect for centers, review days, or early finishers.

Task cards are one of the easiest ways to add movement and engagement to math practice.

Use them for:

• around-the-room review

• partner work

• small groups

• scoot games

• independent practice

You can mix multiple decimal skills without overwhelming students.

Teacher Tip: Decimal task cards work especially well during rotations.

If you need help managing groups at the same time, here’s how I teach small groups without the room falling apart.

Online Shopping Spree

Turn decimal practice into a real-world shopping game students will love.

Give students a budget and a list of item prices. If approved technology is available, students can also browse a school-approved shopping website to find real prices.

Students must compare prices, add totals, and stay under budget.

Challenge Ideas

1. $25 Budget Challenge

You have $25.00 to spend.

Choose items without going over.

Who gets the most items?

2. Closest to Budget Wins

Spend as close to $40.00 as possible without going over.

Closest total wins.

3. Better Deal Battle

Which costs more?

• Water Bottle = $18.95

• Backpack = $18.59

Explain how you know.

4. Exact Total Challenge

Can you spend exactly $30.00 using 2–4 items?

5. Mystery Cart

Your cart total is $27.48.

What items could be in your cart?

More than one answer may work.

Students build decimal skills while practicing real-world budgeting and decision-making.

Teacher Tip: If devices are available, let students use a school-approved website to compare real prices. If not, use a printed price list or classroom store menu.

Turn decimal review into a fun matching game students will want to play again and again.

Create cards with different representations of the same number. Place all cards face down, then students take turns flipping over two cards to find a match.

Match cards such as:

• model ↔ decimal

• fraction ↔ decimal

• expanded form ↔ decimal

• word form ↔ decimal

Example Matches

• 0.5 ↔ 1/2

• 0.25 ↔ twenty-five hundredths

• 0.7 ↔ 7/10

• 0.43 ↔ 4 tenths + 3 hundredths

If the cards match, the student keeps the pair and takes another turn. If not, flip them back over and play continues.

The player with the most matches wins.

Students build deeper understanding by connecting decimals to fractions, models, and place value forms.

Teacher Tip: Use a smaller set of cards for beginners or mix in more challenging cards for an added challenge.

Students roll dice to create decimals.

Example:

Roll 3 and 7 = 0.37

Then challenge students to:

• make the greatest decimal

• make the smallest decimal

• create a decimal greater than 0.5

• compare with a partner’s decimal

Quick, simple, and effective.

Give students 3 quick decimal problems each day and see if they can finish accurately before time runs out.

Try:

• compare decimals

• write a decimal in word form

• place a decimal on a number line

Make It a Game

• Beat the Clock: Finish before the timer ends

• Streak Tracker: All correct = earn a point

• Level Up Friday: Add 1 bonus problem

• Team Challenge: Partners solve together

This short daily review builds confidence and keeps decimal skills sharp.

Teacher Tip: Perfect for morning work, warm-ups, or exit tickets.
