Math Quizzes on a variety of topics from Grade 7 or 8 curriculum: surface area and volume, algebra, percentage change, coordinate geometry, polygon angles, integers. 17 quizzes in total in Word document format for easy editing.

A set of quizzes to check understanding on a variety of basic algebra concepts (combining like terms, equation solving, inequalities, number patterns)

Six (6) different types of tasks that require students to: - describe steps of worked solutions to equation solving - describe errors in worked solutions to equation solving - write expressions from a description of operations - write equations from a description of operations and solve it.

MYP Style linear patterns task based on the famous painted cube problem. Students are asked to find the equation for number of small cubes with three, two, one, and no sides painted for a larger cube of any side length n. It is valuable as a formative task to help students get used to investigation task structure or possibly as a formative assessment. I would not recommend using it formally as a summative task. It is essentially four mini-investigations in one instead of one investigation whos

An inquiry task where students match equations on cards to graphs of quadratic functions. This forces students to attend to function forms and how their parameters impact the features of the graph. This task assumes prior knowledge of algebraic simplification of binomials and factorization of trinomials. Zip file contains Word and PDFs of 3 files - 6 graphs, cards with function equations, and graphing practice for afterwards.

A set of 9 tasks getting students to investigate linear patterns and to verify and justify their generalization.

A set of 14 quizzes to support a unit on grade 6-7 Algebra and linear patterns.

A guided inquiry task to help students understand the significance of each stage of the function modeling process. One question with structured prompts for the types of things to write about is provided, followed by three practice questions each with data that is approximately quadratic. This may require two lessons, depending on the length of your lesson period. Or it could be done in one guided lesson with the practice questions being assigned for homework.

A guided task to help students develop the concept of factoring. This task assumes/reviews prior knowledge of using distributive property (FOIL) to multiply a binomial by a binomial to make a trinomial. It helps students to see factoring as the reverse process of simplification using the area model of multiplication. This is a set of two tasks for trinomials where a=1 and for trinomials where a is not equal to 1. It is possible that you might do this in two separate lessons to help students dig

A structured inquiry task to draw students' attention to the connection between quadratic function equation forms and their graphs. This is a much more structured inquiry that draws more explicit attention to the parameters by prompting students to factorize or simplify equations to convert one form to another. This draws the students' attention to the connections between the geometry and the algebra.

MYP Style (criterion B Investigation and criterion C Communication) linear patterns task. It is valuable as an introduction to investigation task structure or possibly as a formative assessment. It would require doing some linear patterns in class informally (without showing students how to make equations for linear patterns) and then using this to help the students generalize how to do it, with discussion and debrief afterward to ensure all students understand the concept. It is not intended t

A test structured by MYP criterion A levels checking students' understanding in combining like terms, exponent laws, equation solving, equation rearrangements, expanding and simplifying, and variable substitution. Can also be used as a diagnostic assessment of students' prior algebra knowledge in more advanced grade levels with students who newly arrive at your school or students who may have knowledge gaps. Can also be used for upper elementary grades if algebra is part of your curriculum.

MYP Style linear patterns task based on number of persons seated at tables. It is valuable as an introduction to investigation task structure or possibly as a formative assessment. It is debatable whether it could be properly used as an investigation. On one hand, students find a linear pattern equation for rectangular tables then apply this idea to finding an equation to trapezoidal tables - so in that sense they apply their pattern finding to a new context. On the other hand, one could see thi

Four Tasks for introducing and practicing finding equations for linear patterns. These tasks prompt students to begin asking the question "how do I know this is true?"

A guided inquiry task to help students see the features of quadratic graphs that are linked to the different equation forms of a quadratic function (vertex form, factored form, standard form). I have available another task that does this, but that task provides context questions in each of the available forms. This task provides only equations to graph with the help of tables of values and the GDC. Since this task is context free, it can help strip away layers of complexity so students may focus

An investigation task which challenges students to use their knowledge of the pythagorean theorem to create a general equation for the length of a helix. Potentially could be developed into an assessment task.

A mathematical investigation where students are guided to discover the algebraic method of substitution for solving a system of linear equations.

A guided task with engaging questions based on real-life data scaffolding the linear modeling process.

This is an inquiry task one can use to guide students to developing a formula for simple interest and compound interest.

A mathematical investigation of slope and y-intercept in y=mx+c, the slope-intercept form of a linear function equation.
