The Greedy Triangle

What does Similar Mean in Math?

• Same shape
• Could be different size, colour etc. the colour does not affect what is happening mathematically

Teachers can use the smart board as an effective tool to teach Geometry for example using the smart board to demonstrate shapes that are congruent or similar. The smart board can be a great interactive way to demonstrate these shapes and have students come up to the board and rotate and move the shapes around to examine the relationships between the shapes. Mathematical vocabulary is a great way to start a class and ensure that the students are understanding the concepts before solving problems.

With regards to the topic of symmetry it is important to use real-life examples so that students understand what symmetry means. On both sides of the line of symmetry the shape is equal. Students can also use the smart board to understand that if you fold along the line of symmetry both of the sides are equal.

Using Children's Literature to Teach Math Concepts






There are many examples of children's literature that can be used to teach math concepts to students such as The Greedy Triangle by Marilyn Burns or her other novel named Spaghetti and Meatballs For All A Mathematical Story to teach perimeter and area. Reading to students aloud allows to involve them and make it engaging. It allows you to introduce topics and everyone enjoys being read to even older students.

Development of geometric thinking is key to the success of students in Geometry. It is important that students have a spatial experience and that problems include every day life scenarios. The best way for students to really understand Geometry is for them to be touching it, moving it, and cutting it. When students can physically experience geometry they are able to clearly understand the concepts. In Geometry all students should be using manipulatives because it develops a different area of the brain that is crucial for understanding.
