Hawaii Grade 3 Math

Try the original problem

Four boxes hold eight craft sticks each. A teacher also brings 19 loose sticks. How many sticks are available altogether? Write an equation with s for the total and explain why the loose sticks are added after counting the boxed sticks.

Follow the reasoning

The four equal boxes contain 4 × 8 = 32 sticks. The loose sticks are a separate group of nineteen, so s = 4 × 8 + 19 = 51. A reasonable estimate uses about twenty loose sticks: thirty-two plus about twenty is about fifty-two. The exact result of fifty-one is close to that estimate and includes every stated stick once.

Check a common wrong turn

The expression 4 × (8 + 19) would put nineteen extra sticks into every box, creating four groups of loose sticks instead of the one group given. Adding 4 + 8 + 19 also treats the number of boxes as if it were a number of sticks. Label what each number counts before calculating. Multiplication counts the equal groups; addition combines the boxed and loose totals.

Transfer the idea

Change the task to three boxes of nine sticks plus 16 loose sticks. Explain t = 3 × 9 + 16 = 43 and check it with an estimate. Next, keep the total of fifty-one from the first task and ask how many would remain after giving away seven: forty-four. Treat that as a new follow-up question rather than add an unstated third step to the original problem.

Selected references from Hawaiʻi’s revised mathematics document

The Hawaiʻi mathematics standards directory links the HCCS-M document approved in 2026. Its announced implementation schedule is elementary school in 2027–28, middle school in 2028–29, and high school in 2029–30. These references identify this activity’s focus in the revised document; they do not claim every school has already implemented it. Confirm the school’s current course and transition plan, including the placement of Grade 6.
