We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.
If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.
Therefore, the rounded number of 745 to the nearest ten is 750.
\(18 × 40 = 720\)
\(64 ÷ 8 = 8\)
\(25 × 50 = 1250\)

Frequently Asked Questions
What are SBAC scores used for?
SBAC scores show how well your child met grade-level standards in math and English. Schools and states use them to check how students and programs are doing, and teachers may use them to plan support for the next year. For a 3rd grader, the score report also breaks math into areas such as concepts and procedures and problem solving, so you can see where to practice.
Does SBAC testing matter for 3rd graders?
SBAC testing matters as a checkpoint, but it is not usually a pass or fail test for a 3rd grader. It is often the first year your child takes the state math test, so the score sets a baseline for later grades. It can guide extra help or enrichment, so a calm, well-prepared test day is worth the effort.
What is the SBAC math performance task for grade 3?
The SBAC math performance task is a multi-step problem set around one real-world situation, such as planning a class garden or a school party. Your 3rd grader reads the scenario, then answers several connected questions that use multiplication, area or fractions and explains their thinking. Unlike the adaptive part of the test, every student gets the same type of task.
Is CAASPP grade 3 math the same as SBAC?
Yes, for math. In California, the CAASPP grade 3 math test is the Smarter Balanced (SBAC) assessment, so SBAC practice questions fit well. CAASPP is the name of California's full testing program, which also includes other tests. Third graders take the math test online in spring, with an adaptive section and a performance task.
How can I improve my 3rd grader's math skills?
Start with multiplication and division facts through 10 × 10, because so much of 3rd grade math depends on them. Five minutes of daily fact practice, plus one word problem where your child explains each step, makes a real difference. Use everyday moments too: measure a room to find its area, or split a pizza to talk about fractions like 1/4 and 2/8.
Where can I find an SBAC practice test for grade 3 math?
Smarter Balanced offers free online practice and training tests that use the same tools as the real test. A 20-question 3rd grade SBAC-style practice test with worked answers adds extra content practice. Let your child try the first one untimed, then go over every miss together and focus the next week on the weakest topic.
