Mental Math Challenges: Developing Speed and Accuracy
1st - 2nd
In these mental math worksheets, students complete an addition tapestry square and use the answer key to color in the grid. Students then complete a timed one hundred question subtraction worksheet.
Notes to Quadratic Equations
In this quadratic equations activity, learners read notes about graphing, factoring, square roots, completing the square, and the quadratic formula. Students read 2 1/2 pages of notes.
Completing the Square
Students explore problem solving through completing the square of a number. After a teacher demonstration, students solve squares of problems by beginning with simple squares and then culminating in solving a squared polynomial. They work on the board and at their desks to solve quadratic equations. In pairs, students complete worksheets.
Application of Completing the Square
The class applies their existing knowledge of perfect square quadratics to complete the square in a problem-solving context using dinner napkins. TI-Nspire calculator and application required.
