# Real World Problems & Lessons

Below are Three - Act math tasks and lessons I use with my classes. If you have never taught a lesson like these I suggest you start with Dan Meyer's post. Feel free to use and edit these lessons. Click away and read about each lesson.

### Flippity Flip Bottle Flip

This flipping active activity blends volume of cylinders with rates of change and linear relations.

### Really Big Lights

How big are those holiday lights? How many lights will we need to string up. Use proportional reasoning to help answer these questions.

### Turbo Texting

Students break out their devices and text away to discover the relationship between the length of a message and how long it takes to text it.

### Perimeter Jumble

This takes the classic maximizing the area of a rectangle problem and adds elements of curiosity and purposeful practice to help reveal the relationship.

### Energy Bites

A yummy lesson where students use volume of cylinders and spheres to determine how many energy bites are made from a recipe.

### Pentomino Puzzles

A Hands-on activity is blended with interactive technology. Students begin with puzzles but ultimately create algebraic expressions and solve equations.

### Pumpkin Timebomb

This fall themed activity asks students to predict how many rubber bands will implode a pumpkin. Use data collected from over 120 exploded pumpkins and create scatterplots to make predictions.

Promote literacy while learning math! Students calculate and track over time their words/min reading rate. Students will also explore the relationship between fast reading and comprehension.

### Trashketball [3 Day lesson]

In this multi-strand lesson students will use estimate and calculate how many paper balls fit in a bucket. They then will race to see who can make more shots into the bucket in a minute.

### Make it Parallel

Students explore properties of parallel lines & transversals. They will create parallel lines on the floor or outside with chalk, and finally use Explain Everything to answer problems.

### Dora to the Rescue

Finally teach collecting like terms and the distributive property with context! Find the perimeter and area of a counter top using only Doras!

### Is Lego Gender Biased?

Use unit rates to help make decisions in consumer gender issues. Is Lego charging more for Disney Princess kits vs. Star Wars kits?

### Corner to Corner

Students use the Pythagorean Theorem to find the length of rope.

### R2D2 - Post-Its

A rich area of rectangles problem with a sequel that extends into optimization.

### Clash Modelling

Does the cost of wait time in the game Clash of Clans follow a linear, quadratic, exponential, or other model?

### Smart Car Smash

Use proportions to determine how many bird craps could crush a car.

### Proportion Explosion

When will a water balloon explode? How much water does it hold? Use proportions to help!

### Minnie's Juice

How many juice boxes will it take to fill Minnie's Cup! Use Volume of prisms and cylinders.

### Crazy Taxi

How does a taxi charge its fare? Would you ride this taxi? Write linear equations to represent the fare.

### Vroom Vroom

A inquiry activity with a little competition. Who can get their car to the finish line closest without going over? Use lines of best fit

### Dark Side

In this sequel to Dan Meyer's Double Sunglasses use exponents to see how many sunglasses you need to add go to the dark side!

### Filling It Up

Use linear relations to determine how many cups to fill a jug of water with an object inside.

### Many Many Volumes

Crowd source the relationship between the volume of a box and the height of the box. Build boxes and use Desmos to investigate.

### Popcorn Pandemonium

Students experience rates of change in a race to see who will eat the most popcorn.
