Using calculators, students will gain familiarity with the patterns that occur when multiplying by decimals. They'll note these patterns and use them to make predictions before checking with their calculator.
In this video, students will investigate how to round to numbers other than multiples of ten. What if we want to round to the nearest 9, 12, 52, or 75?
In this math curiosity, students investigate this fascinating pattern: every positive integer can be written as the sum of four (or fewer) perfect squares.
In this math curiosity, students fill in a square using a set of integers so that each row, column, and diagonal have the same sum.
Students will investigate the curious question: How few colors do you need to color in *any* map?
In this video, students will factor 365 in an attempt to create a better system of months and weeks.
To better understand place value, we venture beyond the decimal number system and explore a Base 9 system. Students will be exposed to ancient Babylon's Base 60 system and computers' Binary and Hexadecimal before creating their own number system!
In this series, students will investigate the rules of the three angles in a triangle.
Students will investigate symmetry in the alphabet, forming words with reflective symmetry, and eventually creating full sentences.
Students learn to group a set of quadrilaterals into flexible categories.
Students learn about parallel and perpendicular lines and then hunt for examples of both in pieces of art.
Students learn about lines, line segments, and rays with a focus on some fascinating aspects of infinity. In the end, they ponder what one type would think about another.
In this lesson, students will deduce the formula to find the area of a triangle, then use that to decompose more complex shapes.
Students will investigate the box office returns and critical acclaim of a set of movies. After gathering their data, they'll graph it on a coordinate plane and look for trends and outliers, and then make a prediction. They'll also create line graphs and use this data to decide if another movie in the series should be made.
In this video, students will calculate the volume of laptops using the formula for the volume of a rectangular prism. First, they'll find five laptops from across history and calculate their volumes. Then, they'll draw them in 3D using some cool grid paper. Students will then explore equivalent volumes before finally building a scale model of a laptop.
How much would it cost to fill up a car with liquids other than gasoline?
Here's a math curiosity involving squares and odds that turns out to be true for every case.
Students will work with authentic data to investigate th
Students will produce a multi-line graph, calculate averages, and calculate ranges using positive and negative temperatures.
Students will double a single dollar once per day and discover how long it takes to reach $1 million. Along the way, they'll move from repeated multiplication to using exponents.
