solve one-variable linear equations with natural number solutions; verify the solution by substitution

How Bloomi helps with this

This is a NAPLAN-year topic. Bloomi teaches it with a short explainer, guided practice, and NAPLAN-style questions — every one traceable to this exact code.

What this looks like in the classroom

• recognising that solving an equation is a process of determining a value that makes the equation true; using substitution to determine whether a given number is a solution to an equation or not
• solving equations using concrete materials, the balance model, and backtracking, explaining the process
• solving linear equations such as \(3x+7=19\) algebraically, and verifying the solution by substitution
