Target 1​

Lesson Type:

New

Number Operation

:

Operational Relationships

Use properties of operations as strategies for solving problems.

Supporting targets:
1:

Identify the Commutative Property of Multiplication.

2:

Understand that a factor can be broken apart and the parts can be multiplied by the other factor and still result in the same product.

3:

Identify the Associative Property of Multiplication.

4:

Understand that the way in which three or more factors are grouped in a multiplication problem does not affect the product.

5:

Understand that changing the order of factors, does not change the product (Commutative Property of Multiplication).

Grade:

4th

Vocabulary:

Commutative Property of Addition/Multiplication, Associative Property of Addition/Multiplication, Factor, Product

Activities:

  • Reviewed and discussed the Associative Property of Addition and related it to multiplication, finding direct similarities.
  • Reviewed and discussed the Commutative Property of Addition and related it to multiplication, finding direct similarities.
  • Solved multiplication problems with 8 factors using either commutative or associative properties, finding a better or more effecient way of ordering or grouping the factors.
  • Created array models to act as visual representations of how the Commutative Property of Multiplication worls.

Target 2

Lesson Type:
New
Number Operation
Computation
Multiply within 1,000.

:

Supporting targets:
1:

Understand there are many ways to multiply multi-digit numbers.

2:

Explain how different methods produce the same product (how each method is doing the same thing).

3:

Understand the role of place-value in multiplication strategies.

4:

Use the standard algorithm for solving multi-digit multiplication equations.

5:

Grade:

4th

Vocabulary:

Lattice Multiplication, Place Value, Factors, Product

Activities:

  • Reviewed steps in solving multi-digit multiplication problems using the standard algorith, while discussing the importance of place values.
  • Students were introduced to Lattice Multiplication, in which a the products of each single-digit factor are recorded in a grid, which are then added in diagonals (the place values).
  • Compared Lattice Multiplication to the standard algorithm and discussed their similarities and differences, as why some students may choose the Lattice method over the standard.
