Math:

This week in math the students will continue learning about the commutative property to solve word problems using arrays.  They will use the distributive property as a strategy to find related multiplication facts.  The students will apply the distributive property to decompose units and will begin solving two-step word problems involving multiplication and division and assess the reasonableness of answers.

Example of solving word problem using arrays and commutative property:

Ms. Williams draws the array below to show the class seating chart.  She sees the students in 4 rows of 7 when she teaches at the front board.  Use the commutative property to show how Ms. Williams sees the class when she teaches at the side board.

This array shows 4 rows of 7                             

                                                                                                                                                                 

This array shows 7 rows of 4

Things to practice at home:

Practice multiplication facts 2-10

Use arrays to model multiplication (2 x 5 or 2 rows 5, 4 x 4 or 4 rows of 4)

Continue practicing math facts using distributive property to break apart large multiplication facts.

Write word problems and solve using tape diagrams or number bonds.

Science:

This week in Science, we will discuss ways to collect and record data during investigations.  We will continue our discussion on how scientists use their observations to infer and make explanations during their explorations.

Math:

This week in math, the students will solve two types of division situations.  Division problems where the group size is unknown and problems where the number of groups is unknown using factors of 2, 3, 4.   Students will use tape diagrams and arrays as tools to compare and analyze problems.  Students will use arrays and tape diagrams to practice solving division problems and transition to problem solving using abstract division and multiplication equations. The students will skip count objects in models to build fluency with multiplication facts using units of 4.  We will continue using the distributive property of multiplication to solve math problems. 

Example of tape diagrams:

                                    

                                 

Things to practice at home:

Practice labeling tape diagrams to solve problem situations (homework problems this week include tape diagrams for practice).  Ask the following questions as you are solving problems:

·         Am I looking for a part? 

·         Am I looking for a number of parts? 

·         Am I looking for the whole amount?

·         What is my model showing me?

Discuss and practice analyzing problem situations comparing different unknowns. 

Continue using arrays to help solve multiplication problems using the distributive property (break apart property) to solve multiplication problems.

Practice multiplication facts (2, 3, 4, 5)

Science:

This week in Science we will discuss science safety rules and how scientists observe and infer during their explorations.  We will discuss the importance of scientists maintaining accurate records and communications.

                              

Week of September 3, 2018

Math:

This week in math, the students will begin to find related multiplication facts by adding and subtracting equal groups in array models.  They will model the distributive property of multiplication with arrays to decompose units as a strategy to multiply.  The students will model division as the unknown factor in multiplication using arrays and tape diagrams.  They will also interpret the quotient as the number of groups or the number of objects in each group using units of 2 and 3.

Examples of distributive property using arrays:

Things to practice at home:

Practice multiplication facts 2-10.

Create multiplication and division word problems to solve using arrays, equal groups, and multiplication facts.

Practice the commutative and distributive properties of multiplication.

Science:

This week in science, we will continue our discussion on "testable questions".  We will be conducting an experiment to try and determine which of the different kinds of cans of soda float.
