TEKS Math Standard: 5.1.C
select tools, including real objects, manipulatives, paper and pencil, and technology as appropriate, and techniques, including mental math, estimation, and number sense as appropriate, to solve problems
Contig
Roll three dice and combine them using any mathematical operation. But be strategic to maximize your points!
Math Curiosity: Magic Triangles
Can you make each side of this triangle add up to 9 using the digits 1-6?
The Heaviest Pumpkin
How heavy is the world’s heaviest pumpkin when measured in Mr. Byrds?
An Olympic Sized Pool and Lots of Pasta (Episode 2)
How many pounds of pasta could you cook using the water in an olympic-sized pool?
Measurement: An Elephant
What if I told you that an elephant weighed a back-breaking 176,000? Could you figure out the unit I’m using? But… how many corgis would that be?
Measurement: A Long Movie
What if I told you a movie was a whopping 0.017 long? Could you figure out the unit I’m using? This lesson packs in strange measurements of time as well as tiny decimals.
Measurement: How Big is this Bathtub?
So, if I told you a bathtub holds 640 of water, which unit would make the most sense?
Measurement: How Old Is Mr. Byrd?
What if I told you that I’m 341,640 old? Could you figure out what unit I’m using? Hint: it’s not years!
Addition: 3 Digits Plus 2 Digits (Multiple Solutions)
Typical practice problems don’t move students up Bloom’s Taxonomy. With this framework, you’ll see kids stop and really think about how to approach multi-digit addition.
Subtraction: 3 Digits Minus 2 Digits (Multiple Solutions)
Typical practice problems don’t move students up Bloom’s Taxonomy. With this framework, you’ll see kids stop and really think about how to approach multi-digit subtraction.
Disneyland Parking Structure Math Project
Your students will use estimation strategies to figure out how many parking spots are there in the parking structure at Disneyland? And you bet I reveal the real answer!
Parentheses: How big of a change can they make!?
Once students understand the order of operations, they often just get stuck doing increasingly difficult practice problems. That’s a sure-fire way to squelch learning, though. Here, students determine where to place parentheses to make the greatest change in an expression.
How Many Ways: Times Equals Times
How many different ways can you make this math statement true using only the digits one through nine?
How Many Ways: Order of Operations 1
How many different ways can you make this math statement true using only the digits one through nine?
Calculators, Patterns, and Multiplying By Decimals
Before teaching students the procedure for multiplying with decimals, how much can they intuitively glean from a structured play session with calculators?
Rounding Numbers (But Not To 10)
What could we possibly do to make rounding more interesting for students who already get it? In this series, students consider how they might round to values other than “the nearest 10.” How, for example, do we round to the nearest 9? 7? 15?
Place Value (Beyond Base 10)
Place value is something we cover in elementary school. It seems simple, but I’d wager that very few adults really understand the topic. I sure didn’t until I worked with non-base-10 number systems in college. Your students can get a taste of this mind-boggling experience by imagining what it would be like if we didn’t have the number 9. What would each digit represent then?
Finding The Volume of Laptops
How has the volume of laptops changed over time? You know you want to check out how huge those first versions were!
Math Curiosity: Waring’s Conjecture
So, can you write every odd (greater than 3) as the sum of three primes?
What Do Mean and Median Mean?
When will mean and median give us different results?
Percents and Credit Cards
Let’s buy something expensive with a credit card and then make only the minumum payments!
Discovering Pi With Sticky Notes
Pi is mysterious and strange! Why not let students discover it on their own?
How Many Students Can Fit On The Playground?
So… just how many kids could we cram onto the playground?
The Game of 100
Who can get to 100 first in this simple, but delightful, math game?
