For this activity, I let the students work in pairs. I give each pair an Add Fractions with Unlike Denominator.docx activity sheet, along with the Multiplication Chart.pdf and fraction strips they already have at their desks (MP5).... to add fractions the denominators must be the same. when you have unlike denominators find the LCM and rename the fractions Well first of all let's say you have one over seven and one over five ok so you multiply the denominators the bottom numbers ok so now both bottom numbers are 35 so now first let's work with 1/7 so now it's just the bottom

Adding and subtracting unlike fractions. This fifth grade lesson teaches how to add and subtract unlike fractions (fractions with different denominators).... Problem: A pizza restaurant had two equally-sized pizzas, each sliced into equal parts. At the end of the day, there was a third of one pizza, and a sixth of another pizza left over.
