# Sandee Beech▸ U4: Math Connections

Students will learn how to create 2D and 3D shapes, discuss: right angles, acute angles, obtuse angles and reflex angles. They will find ‘real world’ objects that are different types of angles and guesstimate approximate degrees. Students will create these objects on Scratch2 in least amount of code and produce a pattern/design as their final assessment submission.
Resources needed: Scratch2.com, code.org,
Lesson 1
Students hand draw 2D and 3D shapes. Teacher discusses the different angles (inside and out) of each angle with the knowledge of 360° as a total amount. Students practice using a protractor drawing and labeling angles.
Lesson 2
Class will investigate angles in school environment and discuss reasons/purpose for established angles on ‘real world’ objects. Students use Venn diagram to compare and contrast an object using original angle and a student created new angle.
Lesson 3
Using Scratch2, Students will create code for 2D and 3D shapes in least amount of code needed. Students will practice using ‘arcs’ to curve corners and design patterns.
Lesson 4
Students will design a pattern with colour for final assessment submission.
