# Modeling New Cases of an Infectious Disease RLP

This assessment was created in response to COVID-19 to give teachers resources to help them teach about the mathematics of infectious diseases. This assessment asks students to model (investigate) the number of new cases per day for a fictitious disease outbreak. They will then need to use the function that they find to make a determination (solving an authentic problem) about whether the disease is growing too quickly for the local hospitals to handle. The main concept that this assessment is targeting is exponential functions.

# Choosing the Best Heater for Bedroom

Students will be given several diagrams of a bedroom with labeled dimensions of the room and the furniture. They will be tasked with choosing the best possible heater for the room based on several conditions like cost, fit, and space that the heater can heat.

# Coordinate Geometry

This assessment measures the knowledge and skills of students in the areas of coordinate geometry: midpoint and distance between two points, gradient of lines connecting two points, gradient of parallel and perpendicular lines, and x- and y-intercepts of lines.

# Add & Subtract Unit Fractions Investigation

Students in this investigation will explore patterns in relation to the addition and subtraction of unit fractions. First, students will need to come up with their own understanding of unit fractions before considering a pattern for the addition of unit fractions (Part A). Afterward, a more open-ended investigation will need to be carried out regarding the subtraction of unit fractions from each other.
