Maryland MCAP Exam Roadmap

The state assessment measures your understanding of expressions, rational numbers, ratios, and spatial area. Review these core formulas and glossary snapshot terms before starting your review sheets.

📈 Operations & Decimals

Divide fractions by multiplying by the reciprocal (Keep-Change-Flip). For decimals, align decimal places when adding or subtracting, and count spaces when multiplying.

Keeps-Change-Flip: Para dividir fracciones, multiplica por la recíproca.
a/b ÷ c/d = a/b × d/c

⚖️ Equations & Variables

Perform inverse operations on both sides to isolate the variable. Whatever operation you apply to one side, you must apply to the other to keep it balanced.

Operaciones Inversas: Despeja la variable aplicando la operación opuesta en ambos lados.
ax + b = c → ax = c - b

📊 Ratio & Coordinate Area

Determine coordinate distances by subtracting coordinates with matching axes, and build ratio tables to scale units evenly.

Escalar Razones: Multiplica o divide los términos por el mismo número para mantener proporciones.
A : B = (A × k) : (B × k)
🔄 Reciprocal
Recíproca: La fracción invertida.

The multiplicative inverse of a fraction (e.g. reciprocal of 2/3 is 3/2).

⚖️ Inverse Operation
Operación Inversa: La operación que deshace a otra.

Operations that undo each other (such as addition and subtraction, or multiplication and division).

🗺️ Coordinate Plane
Plano Cartesiano: Sistema de cuadrículas con ejes X e Y.

A 2D grid plane formed by horizontal X-axis and vertical Y-axis intersecting at origin (0,0).
