Warm-Up 1
Day 2: Whole Number Operations
Review whole number operations, multi-step thinking, and order of operations.
Student Goal
I can solve whole number problems and use the correct order of operations.
Why It Matters
Whole number operations show up inside fraction, decimal, ratio, and geometry problems all year long.
Warm-Up
Warm-Up 2
Find 7 x 8.
Warm-Up 3
Which operation should you do first in 6 + 4 x 3?
Short Lesson
Standard Focus:
NC.6.NS: The Number System
Student-Friendly Standard Goal:
I can use whole number operations and order of operations to solve problems accurately.
- Whole number operations are the foundation for many 6th grade problems. Slow, organized work matters more than speed.
- Use order of operations when a problem has more than one operation. Multiplication and division come before addition and subtraction.
- In a word problem, decide what each number means before choosing an operation.
Guided Examples
Guided Example 1
Multi-Step Pencil Problem
A school buys 6 boxes of pencils. Each box has 24 pencils. The school gives away 38 pencils. How many pencils are left?
Step 1
6 x 24
What should we find first?
Guided Example 2
Order of Operations
Evaluate 8 + 3 x 5.
Step 1
8 + 3 x 5
Which part should be done first?
Practice
Problem 1
Find 438 + 276.
Problem 2
Find 52 x 6.
Problem 3
Evaluate 8 + 3 x 5.
Problem 4
True or false: In 6 + 4 x 3, addition comes before multiplication.
Problem 5
