Use money as a model

• Show that:

  • 1 dime = 10 cents = 1/10

  • 1 penny = 1 cent = 1/100

  • 30 cents = 30/100 = 3/10

Build fractions

• Use:

  • Coins

  • Grids (10×10 hundreds charts)

  • Paper folded into tenths and hundredths

Talk through equivalence

• Ask:
  “How is 3/10 the same as 30/100?”

Practice adding fractions

• Combine amounts like:

  • 3/10 + 4/100

  • Convert to hundredths first and add.

Label everyday decimals

• Prices at the store (e.g., $1.25)

• Battery levels (75%)

Say it three ways

• Example:

  • 0.75

  • 75/100

  • seventy-five hundredths

Draw models

• Shade tenths and hundredths on grid paper.

Write conversions together

• 0.4 = 4/10

• 0.36 = 36/100

Use real-world comparisons

• Compare prices, measurements, or scores.

Ask “Which is greater?”

• Example:

  • 0.62 vs. 0.58

Use place-value thinking

• Compare tenths first, then hundredths.

Use symbols

• Practice writing:

  • 0.62 > 0.58
    
    

Justify thinking

• Encourage explanations using:

  • Words

  • Drawings

  • Place-value charts

Solving Real-Life Fraction & Decimal Problems

(4.NR.5)

• Cooking & measuring

  • Add and compare ingredient amounts.

• Sports and hobbies

  • Track percentages or decimals (batting averages, completion rates).

• Visual models

  • Use fraction bars, grids, or number lines to show thinking.

• Part-whole reasoning

  • Ask:
    “What part of the whole does this represent?”
