Understanding Tens and Number Bonds

Mrs. Fitch introduces a math lesson on number bonds, starting with a warm-up of counting in fives. The lesson progresses to quick recall of number facts, focusing on number bonds to ten and their switches. Students practice these bonds with increasing speed and apply the concept to larger numbers, such as number bonds to 100. The video concludes with a challenge to find number bonds to 20.
