Students will master their ability to differentiate between triangles by playing a great video game. While playing the game, students will focus on finding patterns. When students get lost  they will naturally begin using the problem solving of guessing and checking. Finally students will be using logical thinking by strategically creating triangles within a puzzle in order to gain as many points as possible. By learning from others via discussion and   recording those discoveries as they are found, a growth mindset is encouraged by highlighting the construction of knowledge as a group.

1 Hook

Activity: Presenting

Begin this introduction by explaining that students will be playing the game Dragon Box: Elements where the players are forced to help a unfortunate alien society raise an army by creating different TRIANGLES! Now if that doesn't catch your students attention i don't know what will

So after you have all eyes on you. Begin by giving a basic introduction/review on different types of triangles. 

  • Equilateral
  • Isosceles
  • Scalene
  • ​Acute angles
  • Obtuse angles
  • Right angles
  • etc...

2 Whole group

Before you play the game, assess the students as a whole class about similarities/differences between the types of triangles and what mistakes might easily be made.

For example,

1. Giving students an equilateral triangle and asking ;

  • "What if I classified this triangle as isosceles? Would I be wrong? Why or why not?"'
  • "Is there any other way we could classify this triangle?"
  • "Which kind of triangle is the easiest to recognize? Why? Which is the most difficult to recognize? Why?"
  • "What would be the minimum amount of information you would need to classify a triangle as equilateral/isosceles/scalene?"

​2. Perhaps give students one side length and one angle measure and challenge them to create two different triangle classifications from it and discuss why that is possible.

These questions could also be asked to students individually during independent practice as a way to differentiate for more advanced learners. 

3 Independant Practice

Students will complete levels at their own pace. They will learn vocabulary, and different types of angles. Students will pick up angles and basic rules and patterns of equal measurements. 

The puzzles become challenging and students must think creatively in order to solve problems on their own.

4 Wrap Up

Activity: Assessing

Have this as a exit ticket. You will be shocked at the ability students will be able to discern the differences of different triangles. This is a great app for introducing some background knowledge for your students that you can relate to later on in more complex lessons. This game gets them the basics that they will greatly build upon in later lessons.
