Hi, my name is Marija, and today I'm gonna show you how to teach mixed numbers in third grade. So mixed numbers are first introduced in third grade when we talk about having wholes as well as parts. So, let's say we show the children there are 2 wholes and then a part of something, so this is where mixed numbers are first introduced. We show them that we count the 2 wholes, and those are written as the whole number, and then the 1 out of 2 is written as the fractional part of the mixed number. So this picture is represented by 2 and a half, 2 wholes in addition to one half of an object. We're also gonna need to teach in third grade how to make these mixed numbers into improper fractions. So, you're gonna teach the students that you multiply the denominator by the whole number, two times two is four, we add the numerator to it to get five, and we keep the denominator that was already there to make it five-halves. So I like to always show the arrow and the plus sign so they have that image. So we multiply the denominator and the whole number, add the numerator, and keep the denominator. That's how you teach mixed numbers in third grade.
