Adding and Subtracting Fractions

Mrs. White from Bing Gate presents a video tutorial on Chapter 3 of Math in Focus, focusing on adding and subtracting unlike fractions, converting fractions to decimals, and using benchmarks for estimation. The video covers methods like the least common denominator and the butterfly method, and emphasizes visual learning through bar models. It also provides strategies for converting mixed numbers and offers resources for parents to support their children's learning.
