How to teach this

Have your child estimate before multiplying: 4.3 × 6 is a bit more than 4 × 6, so the answer lives near 24. If the written answer says 258 or 2.58, the point landed wrong. Keep the two phases separate out loud: "multiply first, place the point last." The decimal gets ignored completely until the final step.

Watch for: Kids line up the decimal points like addition and bring the point straight down. In multiplication you ignore the points until the end, then count places. Kids expect multiplying to make numbers bigger, so 0.4 × 0.7 = 0.28 looks wrong. Multiplying by a number less than 1 gives a smaller answer, and that's correct.

Common questions about 5th grade multiplying decimals

Does 5th grade multiply two decimals together?
Not yet. Fifth grade pairs a decimal with a whole number, like 4.3 × 6, so the place counting rule gets learned with one decimal place in play. Decimal times decimal is the 6th grade sheet.
Should my child line up the decimal points?
No, that's the addition rule. In multiplication the numbers stack right-aligned, the points get ignored until the end, and counting places sets the point.
