Skip count Knowledge:
Students know:
that in multiplication, one factor represents the number of groups and the other factor represents the number of items in each group, and the product represents the total number of items in all of the groups. Skills:
Students are able to:
Use a model or drawing to illustrate the product of two whole numbers.
Write an expression or equation to represent the product of two whole numbers identifying the number of equal groups and the group size. Understanding:
Students understand that:
a multiplication problem can be interpreted as x groups of y objects. Diverse Learning Needs:
Essential Skills:
Learning Objectives: M.3.1.1: Identify and define the parts of a multiplication problem including factors, multiplier, multiplicand and product.
M.3.1.2: Use multiplication to find the total number of objects arranged in rectangular arrays based on columns and rows.
M.3.1.3: Write an equation to express the product of the multipliers (factors).
M.3.1.4: Relate multiplication to repeated addition and skip counting.
M.3.1.5: Apply concepts of multiplication through the use of manipulatives, number stories, skip counting arrays, area of a rectangle, or repeated addition.
M.3.1.6: Apply basic multiplication facts through 9 x 9 using manipulatives, solving problems, and writing number stories.
M.3.1.7: Solve addition problems with multiple addends.
M.3.1.8: Represent addition using manipulatives.
Prior Knowledge Skills:
Recall doubles addition facts.
Use repeated addition to solve problems with multiple addends.
Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.
Understand key words in addition and subtraction word problems. Define subtraction as separating groups of objects, taking from, or taking apart.
Define addition as combining groups of objects, adding to, or putting together.
Represent addition and subtraction with objects, fingers, mental images, drawings, sounds, acting out situations, verbal explanations, expressions, or equations.
Represent numbers with objects or drawings.
Use objects to combine and separate groups.
