In this project you are to construct the letter ‘T’ following given instructions, then construct your own letter from a given set or your own creation.
The objective of this project is to become more familiar with using a variable and to practise manipulating trinomial expressions.
Grading: Please see the grading descriptors for proficient communication and reasoning.
Page Structure
- Title page with your name, date, project title and an introduction that states the objective of the project in your own words. Perhaps also a picture.
- An image of the ‘T’ with three specific values of ‘t’. Demonstrate how to calculate the area for the specific values.
- An image of the ‘T’ with dimensions expressed using the variable ‘t’. Demonstrate how to calculate an expression for the area of the ‘T’ using the variable ‘t’. Verify your expression using the values calculated on page 2.
- An image of your own choice of letter first expressed with values of ‘t’. Explain what the minimum value of ‘t’ must be for every dimension to measure one unit or more. An image of your letter for each of three specific values of ‘t’. Demonstrate how to calculate the area for these specific values. Letter project ideas
- An image of your letter with dimensions expressed using the variable ‘t’. Demonstrate how to calculate an expression for the area of your letter using the variable ‘t’. Verify your expression using the values calculated on page 4.
- An image of your letter with dimensions expressed using the variable ‘t’, along with a list of steps on how to construct the dynamic letter using GeoGebra (either with dynamic points as per the first video or using circles, perpendicular lines and intersections). Include a link to your file.
