Major concepts... math computation, measurement (volume, weight, temperature), and simple ratios. Following a recipe involves understanding and enacting a step-by-step process: applications of mathematical processes such as logic, sequential thinking and following directions. Recipes involve portions and measurements, often needing doubling for a large crowd or dividing for a smaller group, necessitating the application of arithmetic skills with fractions and whole numbers involving all the computational operations: adding, subtracting, multiplying, and dividing.
