Reasoning with Tape Diagrams in 7th Grade Math

This video tutorial covers several math problems for seventh-grade students. It begins with estimating the weight of six apples using multiplication. Next, it involves selecting stories that can be represented by a tape diagram. The tutorial then discusses Andre's plan to save money for a gift, using a tape diagram to calculate weekly earnings after donations. It also includes determining the greatest value among given expressions and solving equations involving negative numbers.
