Area & Circumference of Circles NOTES & PRACTICE

The Area & Circumference of Circles NOTES & PRACTICE

An exceptionally handy educational resource designed with precision for Grade 7 teachers and homeschoolers. It emphasises the 7th-grade Geometry Standard (CCSS.MATH.CONTENT.7.G.B.4) and aids in understanding two principal concepts - calculating the area and surfing through the circumference of a circle while also exploring their intriguing inter-relation.

Resource Elements:

• Discovering Circles Activities: A series of activities introduces different circle sizes and diameters, illustrating how varying circles can still share particular uniform properties.
• Area & Circumference NOTES & Practice: This section directs students towards exercises based on two formulas - for calculating area and measuring circumference, alternating between accurate usage of π and practical application using pi as just 3.14.
• The Relationship between Area & Circumference TASK: Here's where theoretical concepts meet practice! Learners cut up a reconfigured circle into 12 units to create a parallelogram shape, subsequently comparing it with its original circular form.
• TEST PRACTICE Module: Conclude your sessions by testing your students on these new concepts learnt - printable format or a Google Forms format ensures convenient assessments remotely or traditionally.

All modules come with answer keys simplifying grading tasks while enabling student self-checks - fostering self-improvement techniques!

We provide files in universally compatible PDF file types making them transferable across digital or traditional formats – carrying it from classrooms at school to relaxed couches at home seamlessly!

A Learning Experience beyond Ordinary:

No longer is Geometry an abstract concept but a practical subject that invites exciting discoveries with every lesson. The Area & Circumference of Circles NOTES & PRACTICE attempts to bring an engaging and refreshing perspective into Grade 7 geometry learning experiences.

This resource contains the following items:

1) Discovering Circles Activities (Optional):

· Circumference Discovery: Students explore two different sizes of circles paired with diameters of paper.

· Area Discovery: Students explore the area of one circle and are asked to compare it with the area of the circle’s square radius

2) Area & Circumference NOTES & PRACTICE

· Students will learn both formulas for Area & Circumference of Circles

· They will be asked to leave some answers in terms of , while others will require them to use 3.14 for pi.

3) Relationship between Area & Circumference TASK (Optional)

· Students will be asked to compare a circle with 12 pieces rearranged to form a parallelogram

· They will then be lead through questions that should help them arrive at an alternate formula for the area of a circle, based on circumference and radius.

4) Area & Circumference TEST PRACTICE (Printable and version for Google Forms)

5) Answer Key to All Parts
