CODING IN MTH1W

OPERATIONS WITH NUMBERS (B3.2, 3.3, 3.4)

Alter an existing program to perform different operations and test its accuracy in performing calculations with input values, using conditional statements.

Making a Simple Addition Program (TLDSB)

Note: This page has examples in Scratch, which we can use in WRDSB.  The links to Python examples are done in Colab, which we do not have access to in WRDSB.  We suggest using replit.com for Python coding. (Disclaimer: students have to make accounts and their work gets published to the web.  Replit does have good privacy protocols.  WRDSB teachers are encouraged to review apps using the Third Party App policy).

COMPARING UNIT RATES (B3.5)

Alter an existing program to make comparisons between unit rates of items - increase the number of items being compared or change the terms of the situation.

SIMPLIFYING FRACTIONS (pre-B3)

Analyze and test code to simplify fractions. Alter code to accomplish more variations.

Simplyfing Fractions Using Python (WRDSB)

COMPARING EXPRESSIONS ALGEBRAICALLY (C1.3)

Create a program that takes two algebraic expressions and tests them to see if they are equivalent. Students will need to understanding like terms, unlike terms and operations between them.

SOLVING EQUATIONS (C1.5)

Create a program that will solve an algebraic equation with changing coefficients. Students think through inverse operations as they design the program.

Consider combining this task with measurement problems (e.g., solving for the height of a cone, given its volume).

WRITING EQUATION OF A LINE (C4.4)

Students alter code to generate the equation of a line given input valuses, in Scratch.

Slope and Y-Intercept (TLDSB)

MODELLING DATA (D2)

Students take provided data (or collected data) and use an appropriate tool to model the situation.

Consider this example of modelling basketball data from intermediate grades.

Consider this thinking about Mathematical Modelling.

MEASURES OF DATA (D1.2)

Students design programs to determine measures (mean, median, mode, range, etc.) for a given (or changing) set of a data and analyze how changing one or more values affects these measures. It is ideal if this data is real-life or conextual.

Consider using a spreadsheet tool.

Consider this example of Coding and Data where Scratch is used.

BUDGETING (F1.4)

Set parameters for students to create a budget for a hypothetical situation (perhaps a school initiative / event). Students can use a spreadsheet to program fields so that making modifications show immediate effects. 

Creating a Budget Resources (TLDSB)

EduBlocks Example Code for Compound Interest

Google Sheets Compound vs. Simple Interest

Gizmos Compound Interest

CREATE GEOMETRIC DESIGNS (E1.4)

Specify a set of requirements (i.e., geomtric properties) to be met by the geometric design. Students use a program like Scratch to create a design that  meets these requirements. 

Example: We have 90 m of fencing, find the 4 sided shape that optimizes area.

Consider specifying requirements like a Menu Math task.

Consider some of these Coding Challenges for inspiration.

CHANGING DIMENSIONS (E1.4)

What happens to the volume (or surface area) of a figure when I change one, two or three dimensions? What patterns do you notice? Students could use a spreadsheet and learn how to use formulas to explore how changing the parameters may change these measurements.

Scratch Example Right Angled Triangle

EduBlocks Example Volume and SA of a Cube

EduBlocks Example Perimeter and Area Maximization

Infinity Pool (TLDSB)

CHECKING PYTHAGOREAN (SUM OF SQUARES/RIGHT TRIANGLE RELATIONSHIP) TRIPLES (E1.5)

Analyze and alter code to test if three numbers will create a right triangle.

Checking for Pythagorean Triples (WRDSB)
