nikimathnikimath

Radical Equations - 4 Multiple Choice Tests & True Math Story - for Groups of 4

(0)
This activity is designed to be used for groups of 4 members! It includes four different multiple - choice quizzes each of eight radical equations and a brief biographical text of NASA research mathematician Katherine Johnson (to be completed). Students will practice solving radical equations reducible to linear and quadratics. Extraneous solutions are included. The radical equations contain: a monomial and/or a binomial under a radical symbol a radical expression on one side of the equation and a monomial or a binomial on the other side radical expressions on the both sides of the equations (“radical equals radical”) Most of the equations require rearranging and isolating the radical and the rest are set up to square both sides. All the equations require squaring once. Activity Directions: Students solve all the equations. The answers they get will give them pieces of a brief biographic story about the American scientist Katherine Johnson. It can stimulate student interest in Math and provide a role model for all students. Recording sheets are provided for students to show all work. Answer keys are included.

Solving Quadratic Equations - "Burst Balloons" Game for Groups of 4

Solving Quadratic Equations - "Burst Balloons" Game for Groups of 4

(0)
This activity practices solving quadratic equations. The half of the equations are in standard form and set to zero and the other half have one term on the right side of the equation. There are also included incomplete quadratic equations. Solutions are only rational numbers. Activity Directions: Partners will each have their own set of 8 quadratic equations. They solve the first four of them by factoring and the rest – by the most appropriate method they choose. Then they search for the numbers they have found on the “balloons board” - a set of balloons given with numbers and words on them. When students find their answers written on some of the balloons, they “burst”(strike-through) it. The word written on this balloon is eliminated too. Partners continue solving still that way and at last they will have some balloons “survived” inseparably with the words written on them. They arrange all these words to make a proverb. I have designed THREE DIFFERENT VARIANTS of “balloon boards” so the groups playing different versions to find out other proverbs.(The problems are the same.) All answer keys are included. I hope your students enjoy “eliminating balloons” and searching for wisdom sayings.
Quadratic Equations with Complex Roots - Partner Activity"Make Compound Words"
nikimathnikimath

Quadratic Equations with Complex Roots - Partner Activity"Make Compound Words"

(0)
This activity practices solving complete quadratic equations with complex solutions by completing the square and by the quadratic formula. All the equations have terms on both sides. Partners have similar type of problems so as to meet similar difficulties. They will each have their own set of twelve equations which must be solved by a specified method. The amusing part of this product is creating compound words corresponding to the solution sets of the quadratic equations given. Activity Directions: Partners are instructed to solve half of their problems by completing the square and the other half – by the quadratic formula. Using a table given, they find which two words correspond to the solution set of each of their equations and make compound words. They record their findings in another table provided. Students show detailed solutions on student recording sheets specially designed for this activity or they can solve the problems on a separate sheet of notebook paper. Answer keys are included. I hope your students enjoy this activity.
Solving Quadratic Equations by Factoring -"Hidden Constellations" Group Activity
nikimathnikimath

Solving Quadratic Equations by Factoring -"Hidden Constellations" Group Activity

(0)
This group activity practices solving quadratic equations by factoring. The half of the quadratic equations are in standard form and the other half of them have terms on both sides. The accent is put on finding a common root between two and more equations. The fun part is finding out the configurations of two hidden constellations. Activity Directions: Students will each have their own set of two groups of seven equations. The first group of equations are labeled with big Latin letters and the second group – with small Latin letters. All the equations with one and the same letter have a common root. Partners solve, compare their answers and determine the common root for each group of equations. They record their answers in a table provided on a group response sheet and mark the common root between equations A, then – between equations B and etc. Students are also given a figure with circled numbers called “stars”. Some of these “stars” form configurations of two constellations. The “stars” of the first constellation are numbered with the values of common roots of the equations, labeled with big Latin letters. Respectively, the “stars” of the second constellation are numbered with the values of the common roots of the equations, labeled with small Latin letters. Once students have determined the common roots, they look for their values on the figure and connect the stars with straight lines in a given order so they can find the configurations of the two hidden constellations. At last partners try to identify which are the constellations (Ursa Major and Ursa Minor). Recording worksheets are provided for students to show work. All answer keys are included as well. THIS ACTIVITY CAN BE DIVIDED INTO TWO PARTS!
Rational Equations - Cross Multiplying - Drawing & Coloring Group Activity
nikimathnikimath

Rational Equations - Cross Multiplying - Drawing & Coloring Group Activity

(0)
Students will practice solving rational equations reducible to linear by cross multiplication with this activity. (The types of the problems are described in details in the preview file. All coefficients and almost all of the solutions are integers). Activity Directions: Students work in groups of 4. There are a total of 32 problems. Each member of a group will work through 8 rational equations, where half of them are marked with a flower drawing and the other half are marked with a ball drawing. The flowers and the balls of each partner of a group are colored in one and the same color. Students solve all the problems. They find their answers on a picture of a meadow given and draw a flower or a ball on this picture around their answers. Then they colorize them with the respective color. For instance, if a number on the picture is the solution of an equation marked with a red ball, the student will draw a ball around this number and will colorize it in red. The sum of the answers of each partner is zero. Students recording sheets are specially designed and provided for this activity. All answer keys are included. This activity is engaging and at the same time relaxing. I hope your students enjoy it. NOTE: You will need a** colored printer** to use this activity!
