# Everyday Stuff & Review Ideas

Warmup Ideas

Number Sense

- Modified PEMDAS relay
- Order of Operations Activity with Numbers and Symbols and Possible ‘Answers’
- Cheesemonkey’s helping kids develop number sense using an awesome numberline boardgame

Problem Solving

- Hotel Snap (see Fawn Nguyen’s notes on this lesson here).

**Term 1**

ice Breakers

Multiple Representations

- http://www.visualpatterns.org
- Index of the visual patterns (listed by function family)
- Slope Foldable
- Sarah Hagan’s Slope Name Art
- Sarah Hagan’s Independent/Dependent Variable notes and card sort (scroll down to bottom of post)

Slope-Intercept Form

- Slope & Intercepts from Graph Game
- Stairs and Steepness (Fawn Nguyen)

Systems of Equations

- Diapers: Students create a table, graph and equation to represent and analyze disposable vs reusable diaper costs.

**Term 2**

Linear equations from 2 points

- Domino Effect by Mathalicious

Functions

- Functions Notes
- Sarah Hagan’s Introduction to Relations

Qualitative Graphs

- Distance & Time Graphs (Shell Center)

Simplifying Expressions

- Combine Like Terms Uno
- What’s In the Bag?: Video posted by J. Reulbach. Her students place items in the bag and take them out of the bag and then simplify their resulting expression. So simple. So effective.
- Fruity Like Terms Poster (TPT free)
- Combine Like Terms (When Math Happens)

Solving Equations

- Fawn’s Noah’s Ark (and Factor Craze): students must balance the weight of the animals in the ark
- Imbalance Problems
- Julie’s Monster Math
- Sarah’s use of diagrams/balances for equations (focusing on special case equations with no solutions or all solutions)
- Dan’s Ditch Diggers (equations with zero solutions, no solutions, one solution)

Parallel Lines & Angles Triangles & Angles

- Kathryn’s Angles Formed by Parallel Lines Cut by a Transversal Foldable
- Jessica’s Dance, Dance, Transversal
- Julie’s Transverals, Parallel Lines, and Discovering Angle Properties

**Term 3**

Pythagorean Theorem

- Looking for Pythagoras (CMP Unit)
- The Taco Cart (Dan Meyer)
- Wheel of Theodorus (Goal: Using Pythagorean Theorem, students create their own Wheel of Theodorous and then make this into some sort of creative art work.)
- Kevin’s Shoelaces
- Discovering the Pythagorean Theorem with cm Cubes (Julie Reulbach)
- Barbie Zipline (Andrew Stadel)

Irrational Numbers Volume

- Glasses Task: Volume of composite spheres/cylinders/cones
- Volume of 3-D shapes with Play Doh (Julie Reulbach)
- Discovering volume of cone (Julie Reulbach)

Geometric Transformations

- Entrapment (TPT)
- Transformation Notes (Jessie Hester)

**Term 4**

Integer Exponents

- Cosmic Voyage (IMAX Video zooms in and out to show powers of 10)

Scientific Notation

- dy/dan’s method of introducing scientific notation
- Bryan Meyer’s open-ended Scientific Notation Task

Patterns in Data/Linear Association

- How Much Will College Cost? (Goal: Students analayze data of average college room and board, tuition and fees; create scatter plot; draw line of best fit; and make predictions.)
- Crime Scene (Goal: Students collect data about foot length and height in order to determine the ‘criminal’ teacher who stole items from classroom using only the criminal’s footprint.)
- Barbie Bungee Lesson and Barbie Bungee Video
- Plotting & Predicting Measurements (height, head circumference, foot length, etc)
- Free Linear Regression Calculator
- Crazy awesome Guessing Celebrity Ages Scatterplot lesson by When Math Happens

Categorical Data Systems and Standard Form

- Substitution Stars: Life-changing, yet so simple. You’ve got to read it to believe it.
- Pencils and Pens: Video of Japanese classroom teaching standard form. Interesting to see how they introduce the table!
- I Speak Math’s method for “Solving for Y” (in 2 step equations)
