# Leo's Shapes

In this assessment, students investigate patterns between the number of Vertices (V), the number of Sides (S), and the number of Regions (R) in two-dimensional figures: simple and crossed polygons. Then, after discovering the pattern, students select their 3D solid figure and use their drawings to investigate patterns between the number of Vertices (V), the number of Edges (E), and the number of Faces (F) in these three-dimensional solid figures, including the Platonic solids.

# Planning a Trip

This assessment asks students to help plan a trip around Europe to locations with different time zones. Students must analyze different timetables, with different formatting, to figure out a route for all the places on the trip that minimizes the amount of airtime..

# Creating a Number System

This assessment is meant to be used at the end of a unit that teaches the concept of place value, number base, and expanded notation from an exploration of ancient number systems, such as the Egyptian, Roman, Mayan, and Babylonian systems. Students are asked to create their own unique number system within a given set of loose parameters. The final product is a poster that explains the number system in such a way that classmates can understand how it works by reading each others' poster.

# Cube Might Guy and the Hollows

In this assessment, the cube version of Naruto’s Might Guy (マイト・ガイ), called Cube Might Guy, needs some help exploring some patters! Students are asked to use isometric dot grids to draw hollow square frames, rectangular hollow frames, hollow cubes, and hollow cubic frames. Based on those drawings, students will find, describe, and verify those patterns.

# Odd and Even Factors

A factor, also called a divisor, of a natural number is a number that divides the number without any remainder. For example, the factors of 8 are 1, 2, 4, and 8, because when 8 is divided by either of these numbers, there is no remainder. In this assessment, students investigate positive factors of natural numbers, exploring patterns in the number of factors and the number of odd vs. the number of even factors.
