Adding and Subtracting Mixed Numbers Using Visual Models

In this video tutorial, Sara and Lilly are making cupcakes and using different amounts of sugar. The lesson demonstrates how to add and subtract mixed numbers with equal denominators using visual models. Sara uses 2 and 2/3 cups of sugar, while Lilly uses 1 and 2/3 cups. The video shows how to combine these amounts to find a total of 4 and 1/3 cups of sugar used. It also explains how to calculate the remaining sugar in the pot by subtracting the used amount from the initial 8 and 2/3 cups, resulting in 4 and 1/3 cups left. The tutorial emphasizes understanding fractions and mixed numbers through visual aids.
