Adding Fractions with Different Denominators Using a Grid Model

This video tutorial teaches how to add fractions with denominators of 10 and 100 using grid models. It explains the concept of equivalence between fractions, common mistakes students make, and provides example problems with solutions. The tutorial emphasizes the importance of understanding denominators and numerators, and how to correctly add fractions by converting them to equivalent forms.

What is the purpose of using grid models when working with fractions?

• To make fractions look more complex

• To convert fractions into decimals

• To compare fractions with different denominators

• To simplify fractions to their lowest terms

Why are 60/100 and 6/10 considered equivalent?

• They have the same denominator

• They are both improper fractions

• They occupy the same point on a number line

• They have the same numerator

Which of the following is a common misconception about fractions?

• Fractions are always less than 1

• Fractions with different denominators cannot be compared

• Fractions with the same numerator are equivalent

• A larger denominator means a larger fraction

What mistake do students often make when adding fractions?

• They subtract the numerators and add the denominators

• They add the numerators and denominators separately

• They divide the numerators and multiply the denominators

• They multiply the numerators and denominators

How should fractions with the same denominator be added?

• By subtracting the denominators

• By multiplying the numerators

• By adding only the numerators

• By adding both numerators and denominators

What is the first step in adding fractions with different denominators using grid models?

• Convert both fractions to decimals

• Multiply the fractions

• Add the numerators directly

• Find a common denominator

When combining fractions on a grid, what does 4/10 convert to?

• 4/100

• 40/100

• 0.4

• 400/1000
