Learning Intention: Students will identify that a unit fraction is one part of a whole; indicate that the more parts a whole is divided into, the smaller the parts will be.
Success Criteria: Students will be successful when they can independently explain numerator, explain denominator, compare fractions using models, and decompose a fraction into a sum of unit fractions with the same denominator.
Essential Questions: - How can I represent these fractions? - What is the relationship between the two fractions?
Fractions are important because they tell you what portion of a whole you need, have, or want.
Fractions are used in baking to tell how much of an ingredient to use.
Fractions are used in telling time; each minute is a fraction of the hour.
Money is another place fractions are used. For example, a quarter is one fourth of a dollar (1/4). A dime is one-tenth, represented by 1/10. We could continue by talking about pennies and nickels.
Subtracting Fractions With Like Denominator Student Work
Learning Intention: Students will add and subtract fractions with common denominators.
Success Criteria: Students will be successful when they can independently add or subtract fractions with denominators of 10 and 100.
Essential Questions: - What is the difference of two fractions? - Which part of the fractions do I add? - Why do I not add the denominators?

Strategy
To subtract fractions there are Two Simple Steps:
Step 1: Make sure the bottom numbers (the denominators) are the same.
Step 2: Subtract the top numbers (the numerators), put that answer over the denominator.
