Learning Goals
- Parts and wholes (fractions)
- Attending to all parts of a multi step problem
- Effeciently and correctly counts money
Curriculum Expectations
- Divide whole objects and sets of objects into equal parts, and identify the parts using fractional names
- Represent and describe the relationships between coins and bills up to $10
- Estimate, count and represent the value of a collection of coins and bills with a maximum value of $10
Activation
Saaruni has 3 coins in her pocket. One-third are dimes, one-third are quarters and the rest are pennies. How much money does Saaruni have?
Lesson Problem
Thinh has 10 coins in his pocket. One-fifth is loonies, two-fifths are quarters and the rest are dimes. He wants to buy a toy at the Dollar Plus store that costs $4.00. Does he have enough money? Justify your answer.
Problem Solving Strategies
- Make 5 equal groups of coins
- Add groups of alike coins first and then add the total money
- Count money value in cents and convert to dollars and cents
- Compare total to $4.00 needed
- Subtract total amount of coins from $4.00 to determine how much more money is needed to buy the toy
Tools
- Paper and pencil
- Four hundreds chart
- Number line
- Coins
Highlights and Summary
- 4 quarters = $1.00
- 2 loonies = $2.00
- Grouping coins that are alike help us to add them
- Fractions tell us how many equal parts to divide the whole into
- Label each part of the fraction as the fraction name (one-third, one-third, one-third)
- When you count the fractional pieces you get the whole (one-third, two-thirds, three-thirds)
Independent Problem
Mahir has 15 coins in his piggy bank. One-fifth are toonies, two-fifths are loonies and the rest are dimes. How much money does he have altogether? Justify your thinking.
Parallel Task
Mahir has 10 coins in his piggy bank. One fifth are dimes, one fifth are nickels and the rest are pennies. How much money does he have altogether? Justify your thinking.
