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.

Two (2) Diagnostic Math Tests - one for start of year with fractions, number, and a variety of other basics to check. Markscheme/solutions provided - one specifically for prior to a percentages unit, checking knowledge and skills in fractions and decimals concepts. No solutions provided. Written for Grade 8, but could be used for Grade 9 and (with perhaps some small adjustments) for younger grades.

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

Inquiry lesson for students to discover logarithm laws. Extension to the proof of the log laws

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 task that provides purposeful practice with integers while challenging students to find the greatest/least sum/product and many other challenges with groups of integers.

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

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

Mathematics Investigation to help students determine the method for finding the result of two optimization problems: 1) the maximum area of a rectangle, given a perimeter 2) the minimum perimeter of a rectangle, given an area

A mathematics investigation of the graphical properties of functions and their inverses. This helps students to discover the reflective property of graphs of inverses and can start students on the process of noticing the relationships between equations of functions and their inverses.

A mathematical investigation of different kinds of function transformations. The task requires use of a graphing tool and leads students to explore vertical and horizontal stretches and compression and vertical and horizontal translations. The task also has students explore these with different functions, which helps them to appreciate the variety of non-linear functions that exist.

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

A mathematics investigation task that challenges students to find the dimensions of a cylindrical coca cola can with the minimum surface area, given a known volume.

A task that provides purposeful practice with integers while challenging students to find the greatest/least difference/quotient and many other challenges with groups of integers. Buy alone or in a bundle

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

An investigation of factors that leverages area and volume to illustrate the difference between prime numbers and composite numbers.

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

An investigation of conversions between fractions and decimals that adds complexity to an upper year review of decimals and fractions

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