Arithmetic Sequences and Series Worksheet

Arithmetic Sequences and Series Worksheet

In all classrooms, there are students with different levels of ability. No matter what concept is being taught, presenting the basics to the class and then providing activities that individualize instruction meets the needs of more students and provides opportunities for student engagement and feeling of success. Writing lesson plans for such classroom interaction can […]


Polar Coordinates – Baby Talk

You’ve heard the saying “talk to me like I am three” when trying to explain or understand something complex. The approach to introducing polar coordinates must be made using that same philosophy. For students to understand how to graph polar coordinates and equations, these lessons must use a scaffolding method where students understand each piece […]

Introduction to Vectors Worksheet

Introduction to Vectors – Navigating the Seas

Early navigators used math to chart their course and stay on it when dealing with factors such as wind and ocean current that affected their journeys. The system left something to be desired regarding accuracy. With the use of Introduction to vectors, your students can complete the activity that is linked below and gain not […]

Ellipses and Circles Worksheet

How to Teach Ellipses and Circles

When students see a concept presented in more than one way, the chances of understanding increase. Many teachers have students draw ellipses and circles by attaching a loop of string to two tacks placed in corrugated cardboard. Students use a pencil to draw the ellipse by placing it at one of the tacks and moving […]
