Strand: OPERATIONS AND ALGEBRAIC THINKING (4.OA)

Use the four operations with whole numbers (addition, subtraction, multiplication, and division) to solve problems (Standards 4.OA.1–3). Gain familiarity with factors and multiples (Standard 4.OA.4). Generate and analyze numeric and shape patterns (Standard 4.OA.5).

Standard 4.OA.4

Find all factor pairs for a whole number in the range 1-100. Recognize that a whole number is a multiple of each of its factors. Determine whether a given whole number in the range 1-100 is a multiple of a given one-digit number. Determine whether a given whole number in the range 1-100 is prime or composite.

• Factor Trail Game
In this lesson students will practice identifying the integer factors of numbers up to 100.
• Factors
This lesson is designed to help students understand factors of whole numbers.
• Finding Factors
This lesson plan's activities give students practice in finding the factors of whole numbers.
• Finding Remainders in Pascal's Triangle
This lesson is designed to reinforce division by using clock arithmetic to find remainders and then find patterns in Pascal's triangle by coloring the remainders in colors.
• Identifying Multiples
Students are given a multiplication table for single digit numbers and asked to color all numbers with specific multiples. The goal of this task is to work on finding multiples of some whole numbers.
• Multiples of 3, 6, and 7
This task investigates divisibility properties for the numbers 3, 6, and 7. Students first make a list of multiples of 3 and then investigate this list further, looking for multiples of 6 and 7.
• Numbers in a Multiplication Table
The goal of this task is to encourage students to study the multiplication table, a familiar object, from a novel point of view. The table shows some, but not necessarily all, factorizations of different numbers. Working through the table to see where different numbers appear, the students will have a good opportunity to observe the symmetry of the table which comes from the commutative property of multiplication.
• Pascal's Triangle
Students will learn about Pascal's triangle and practice their skills in multiplication and division in this lesson plan.
• Sample Scope and Sequence
This sample scope and sequence document for the implementation of the new Math core for Grade 4 based on 160 days of instruction - 14 units.
• Sets and the Venn Diagram
This lesson is designed to help students understand the ideas surrounding sets and Venn diagrams.
• USBE Core Guide (4OA4)
This core guide was developed by USBE and Utah educators.
