This Application Problem is a part of the Lesson 12, Unit 7, Grade 2. We can write 100 cents as $1 in our number sentence. Richie has 24 cents. How much more money does he need to make $1? Scaffold the Application Problem for students who are still having difficulties with part-whole relationships by providing a number bond template and helping them fill it out: "Is 24 cents a part or the whole? How many pennies equal $1?"
