# Q1, W2: August 20-24

Teacher Kristin Andreason 8th Grade Intensive Math 8 2 Unit One: Rational and Irrational Numbers
Standard(s) Taught

Review adding integers (positive and negative numbers)

MAFS.8.NS.1.1:  Know that numbers that are not rational are called irrational.  Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually and convert a decimal expression which repeats eventually into a rational number.

MAFS.8.NS.1.2:  Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximate on a number line diagram, and estimate the value of expressions.

Learning Targets and Learning Criteria
• Students will continue to practice adding positive and negative integers.
• Students will practice solving word problems that involve adding integers.
• Students will be able to decide if a number is rational or irrational
• Students will learn how to approximate the value of the square root of a number that is not a perfect square
Classroom Activities

Monday/Tuesday:

• Reinforce classroom procedures
• Bell Ringer:  6 problems adding integers (go over and review methods)
• Talk about classifying rational and irrational numbers using a flow chart
• Students will then write several rational and then irrational numbers

Wednesday:

• Students will do an “Adding and Subracting Integers Maze” (three versions available at different levels of challenge–students will choose the level they feel comfortable with)
• If they finish, they can play the Dot Game with a partner (also adding integers)

Thursday/Friday:

• Students will do word problem task cards working in pairs (those who did not complete their maze on Wednesday will do that first)
• We will watch the Weird Number video to strengthen number sense and what makes a number rational
• We will talk about squares and square roots and will begin to learn how to approximate square roots to a certain place value and practice using white boards
Assignments Due
• Quizizz assignment on Adding Integers
• Adding and Subtracting Integers Maze
