Applying Multiplication to Equal Groups
Applying Multiplication to Equal Groups is a skill on Pengi from Lesson 7: World's Record Folk Dance in Illustrative Mathematics, Grade 5.
Key Concepts
Property To find the total number of items in a collection of equal sized groups, you multiply the number of groups by the number of items in each group. $$Total = (Number\ of\ groups) \times (Number\ of\ items\ per\ group)$$.
Examples If there are 35 dance troupes and each troupe has 24 dancers, the total number of dancers is found by multiplying $35 \times 24$. $$35 \times 24 = 840\ dancers$$ A folk dance festival has 112 circles of dancers, with 18 dancers in each circle. The total number of participants is: $$112 \times 18 = 2016\ participants$$.
Explanation Multiplication is an efficient method for finding the total when combining multiple groups of the same size. In a word problem, one factor represents the number of equal groups, while the other factor represents the quantity within each group. The product of these two numbers gives you the total quantity across all groups. This concept is fundamental for solving real world problems involving repeated addition.
