A fun 10-minute activity to do with your child!
Your child is learning about rates - a way to compare two quantities with different units (like miles per hour or price per pound). Understanding rates helps with smart shopping, travel planning, and much more! This is an important skill for the Florida FAST test. No math expertise needed!
Find two similar products with different sizes. Example: A 12 oz box of cereal for $4.20 and a 16 oz box for $5.12.
Ask: "Which is the better buy?" Guide your child to calculate unit price: divide price by ounces.
Calculate together: $4.20 / 12 = $0.35 per oz. $5.12 / 16 = $0.32 per oz. The 16 oz is cheaper per ounce!
Try more examples: juice, paper towels, or snacks. Compare different brands and sizes!
"To find the unit price, divide the price by the quantity. The lower unit price means a better deal! Always check - sometimes smaller packages are actually cheaper per ounce."
On a drive, note the distance traveled and time. Example: "We drove 45 miles in 1 hour."
Ask: "What was our speed in miles per hour?" (45 mph). Try with other trips: "We went 120 miles in 2 hours" = 60 mph.
Predict: "If we keep going at 60 mph, how long to go 180 miles?" (180 / 60 = 3 hours)
Gas mileage: "We used 10 gallons for 300 miles. How many miles per gallon?" (300 / 10 = 30 mpg)
"Speed is a rate - miles PER hour. Miles per gallon is also a rate. Rates help us predict and plan!"
Look at a recipe. Example: "Makes 24 cookies using 3 cups of flour."
Find the rate: "How many cookies per cup of flour?" 24 / 3 = 8 cookies per cup of flour.
Apply it: "If I use 5 cups of flour, how many cookies can I make?" 8 x 5 = 40 cookies!
"For unit rates, we want 'per ONE' of something. Always divide to get the rate for ONE unit!"
Just 10 minutes of practice at home can make a big impact on your child's confidence and success. Understanding rates helps with smart shopping, travel planning, and everyday decisions. Thank you for being part of their learning journey!
Su hijo esta aprendiendo sobre tasas (rates) - una manera de comparar dos cantidades con unidades diferentes. Por ejemplo: millas por hora, dolares por libra, palabras por minuto. Una tasa unitaria es cuando tiene "por uno" (como $3 por 1 libra). Para encontrar la tasa unitaria, divide el total por la cantidad. Ejemplo: $12 por 4 libras = $12 / 4 = $3 por libra. Para comparar precios, encuentre el precio por unidad - el mas bajo es la mejor compra! Practique comparando precios en la tienda o calculando millas por hora en el carro. Gracias por apoyar el aprendizaje de su hijo!
