This matching activity practices simplifying radical expressions by rationalizing the denominator. There are included 18 radical expressions as the problems vary in difficulty.
Students simplify the given radical expressions.(The teacher can choose less examples than 18 to be worked on). Each expression is labeled with a large alphabet letter. Then students look for their answers on the answer board. Each answer is labeled with a small alphabet letter. Students connect each problem to its answer (match each large alphabet letter to a small alphabet letter).
Student recording sheets and answer keys are included.

In this 12 questions - partner activity, students will solve systems of linear equations with three variables. The problems are adaptable to all methods ( elimination, substitution, Gaussian elimination, Cramer’s Rule) so the teacher or students can choose the methods they will use. All systems have one and only one solution ( All systems are consistent and their equations are independent)!
The answer of each of Partner’s A problems are the same as the answer of each Partner’s B corresponding problem. (Problems A1 and B1 are corresponding, so as problems A2 and B2 and so on). Students are instructed to check whether their results match. If their answers don’t match, they work together to figure out what went wrong.

three systems of quadratic and linear equations ( having respectively two solutions, only one solution and no real solutions)
three systems of two quadratic functions ( having two solutions, only one solution and no real solutions)
I have created worksheets for students to solve the systems only algebraically and worksheets to solve the same problems only graphically. Each problem has enough space for students to show work. Students are provided with coordinates grids where each axis is labeled using an appropriate scale as dictated by the problem so sketching to become easier. The systems can be solved both algebraically and graphically as well. It is depending on what the teacher decides.
This product can be used as in-class practice, an independent practice, partner activity or group activity (groups of two). It can be also used as an assessment or homework.
Typed solutions are included. All the graphs are drawn in CorelDRAW.
*I have also included cards with the problems and cards with the graphs so this can be also used as a matching activity.

This is an engaging and challenging practice on adding, subtracting and scalar multiplication of matrices. It consists of 8 practice tickets as each ticket contains three related tasks. The answer of the first task is needed for the answer of the second task to be found. The answer of the second task is needed for the third task to be completed. In each task students perform indicated operations to find a matrix. When students have completed the tasks on a ticket they would have found three related matrices A, B and C. If the answer for the obtained matrix C is correct then the obtained answers for the matrices A and B are correct as well.
The matrices included are 4x1, 2x2, 2x3, 3x2, 3x3 and 4x3.
You will need to print, cut and laminate (for durability) the tickets.
Student recording sheets and answers keys are provided.

Students can be organized in groups of 2, 3 or 4. Each member of a group is given not more than 7 problems to work out. The activity can be used to have groups compete with each other. Students of each group will get points for the problems they get right. After working the problems, the points are tallied and the group with the most points win. (I have provided a sample scoring scale – each product of a row and a column gets 1 point).
Student recording sheet and answer keys are included.
These are owl themed task cards on multi-step equations and multi-step inequalities engaging and challenging for your students.

This is a fun matching activity for students to practice finding the inverse of 2x2 and 3x3 matrices. The inverse of matrix can be found using a formula (for 2x2 matrices), the augmented matrix method and/or the adjoint method ( for 2x2 and 3x3 matrices). The teacher has to decide if students will be permitted to use calculators.
There are 8 questions - four 2 x 2 matrices and four 3 x 3 matrices. (All matrices selected have inverses.) Students calculate the inverse of each matrix going with a picture of a boy named. Then they look for their answers in a given table with pictures of girls’ faces and their names and find out who is the girlfriend of each of the boys.
If students cut the cells of the tables, they can match the matrices and their solutions.
The activity can be used individually or in pairs.
Student recording sheets and answer keys are included.
In this 12 questions - matching game, students will solve systems of linear equations with three variables by elimination and substitution or using Gaussian elimination. Cramer’s Rule is another method that students can use to solve ten of the systems. (There is one system that is consistent and its equations are dependent and one system that is inconsistent).
Students find the solution to each of the given systems of equations. Their solutions are written on twelve of 13 fish. When students arrive at a correct answer, they “catch the magic fish” having this answer written on it. It is said that only one fish is not really magic, because it doesn’t fulfill wishes. Students have to find it out.
The activity can be used individually, in pairs or in groups of 3 or 4.
Student recording sheets and answer keys are included.
This is a fun matching activity for students to practice finding determinants of 3x3matrices.
Students evaluate the determinants of 12 matrices labeled (going) each with a mask. Then they look for their answers on a given picture with students’ faces and their names and find out who is hiding behind each mask.
(It could be presented as a story about students who had a masked ball in which the participants attended wearing animal masks. Students decided to reveal each other who had been hiding behind each mask during a special lesson in math on determinants of matrices).
The activity can be used individually, in pairs or in groups of 3 or 4.
Student recording sheet and answer keys are included.
This is an engaging and collaborative partner activity for students to practice finding determinants of 2x2 and 3x3matrices.
There are 20 questions to be solved. Partner A start solving first. He finds the determinant a of his first problem (matrix) and gives his answer to his partner. Partner B takes the answer a of his partner and plugs it into his first matrix to find its determinant b. Then partner A takes the answer b and plugs it into his second matrix to find its determinant c. The activity goes still the same way - partners must use the answer from the previous question to substitute into the next problem. Students are given the final result so that they can check whether their work is correct.
Answer keys are included.
