Numerical Methods of Integration
Students review Riemann Sums with rectangles, used to approximate the area under a curve. They listen as the teacher introduces the Trapezoidal Rule to approximate the area under a curve. Students use Simpson's Rule to find the area...
Curated OER
Expanded Form
Students are introduced to the concept of expanded form in a lecture and a class discussion. They write numbers in expanded form using words only, numbers only and numbers and words.
Curated OER
Ordinal Numbers
Introduce ordinal numbers with this simple teaching tool. Young mathematicians trace numbers from 1 to 5. Then they circle the object in a row of 5 that represents the numerical place of the number they just traced. Example: Students...
