Description: Updated as of 2nd October 2021. This deck consists of 31 boom cards that introduce students to subtracting mixed numbers by regrouping with the use of a digital fraction work mat. There are 6 different types of questions that will guide students to practice how to subtract mixed like and unlike fractions. Engage your students with 3 interactions: Fill in the Blanks, Drag and Drop, and Multiple Choice. Cards are NOT set to randomize as cards are arranged in increasing difficulty. This is taught in Singapore Primary 4. 31 Boom Cards | 6 Question Types 1 Notes Identify The Correct Model x5 2 Steps Like Fraction x5 2 Steps Unlike Fraction x5 1 Step Like Fraction x5 1 Step Unlike Fraction x5 Unlike Fraction + Rearrange Own Models x5 Subtracting fractions with denominators of given fractions not exceeding 12 and not more than two different denominators Students will have a fraction work mat that acts as a visual aid. Students will learn what does a mixed number really means by first learning how to identify the correct models in the fraction work mat. Students will learn how to borrow 1 whole by shifting the model from the whole number to the fraction to visualize it. Students can also use the slash to visualize subtracting fractions. They will type the regrouped mixed number and solve for the answer. Students need to simplify the answer if required. For 1-step like and unlike mixed fractions, students will only rely on the colorful fraction mat
