1. Understand the Question

compare

How do the phrases 'at least' and 'at most' change which inequality symbol you choose compared to 'more than' and 'fewer than'?

Your job: Answer the question. Use math evidence. Explain how the evidence proves your answer.Responde la pregunta. Usa evidencia matemática. Explica cómo la evidencia demuestra tu respuesta.

2. Plan Your Math Words

Check at least two words you will use.

Inequality — A math sentence that compares two sides with <, >, ≤, or ≥.Desigualdad — Una oración matemática que compara dos lados con <, >, ≤ o ≥. Greater than — The > sign, showing one number is bigger.Mayor que — El signo >, que muestra que un número es mayor. Less than — The < sign, showing one number is smaller.Menor que — El signo <, que muestra que un número es menor. At least / At most — 'At least' means ≥. 'At most' means ≤.Al menos / A lo más — 'Al menos' significa ≥. 'Como máximo' significa ≤. Variable — A letter that stands for an unknown number.Variable — Una letra que representa un número desconocido.

Say it first: Say your idea to a partner or quietly to yourself before you write.Di tu idea a un compañero o en voz baja antes de escribir.

'At least' uses ___ because it ___ the number, but 'more than' uses ___.'Al menos' usa ___ porque ___ el número, pero 'más que' usa ___.

3. Build Your Explanation

Model the parts: This model shows the parts of an explanation. It does not answer your writing question.

Claim: The age could be 18 or any number greater, so it is not a single value.

Evidence: Students explain that 'at least 18' allows many values (18 and up), so an inequality with ≥ captures it while an equation would force one value.

Reasoning: This evidence connects the definition of inequality to the mathematical claim.
