Features

Every lesson of the unit, in the same order as the test
Find the value of a digit, and write numbers in expanded form and from words
Round to the nearest ten and to the nearest hundred, on a number line and without one
Halfway numbers such as 645 and 350, and numbers that round up into the next place
Estimate a sum and a difference, and use an estimate to check an answer
The last four questions (thousands in base-ten blocks, ordering four-digit numbers, one number shown many ways, and rounding to the nearest thousand) are for the states that teach them in 3rd grade
Answer keys name the lesson and skill of every question

How to Use This Pack

Two pages that go over the whole unit on place value, rounding and estimating, to do together the day before the test. Its 12 questions follow the test's, in the same order, with other numbers; question 10 orders four-digit numbers where the test compares them. Questions 9 to 12 are for the states that teach them in 3rd grade, as on the test. There is no Score line: it is practice, not a grade. The pre-check and the unit test are packs of their own.

In the Classroom

Do the review together the day before the test, with a number line on the board. Work a question, then let students try the next one on their own, and stop on any that trip up more than a few. Leave out the questions from 9 to 12 that your class does not learn. The keys name each question's lesson, so a question the class misses points to the lesson to go back to.

At Home

Use the review as practice before a test at school. Ask your child which two tens or hundreds a number is between, and which one it is closer to.

Tips for Success

Ask "which two hundreds is it between?" before every rounding
Point to the halfway mark on each number line
Remind students that a number exactly halfway rounds up
Keep a number line on the board
Go back to the lesson the key names for a question the class misses

Common Core Standards Alignment

This pack supports the following Common Core State Standards for Mathematics:

2.NBT.A.1a See ten tens grouped together as one unit called a hundred.
2.NBT.A.1b Know that 100, 200 and so on up to 900 mean 1 to 9 hundreds with no tens or ones.
2.NBT.A.3 Read and write numbers up to 1,000 as digits, in words, and in expanded form (like 300 + 40 + 7).
2.NBT.A.4 Compare three-digit numbers by looking at the value of each place, and record the result with >, = or <.
2.NBT.B.7 Add and subtract to 1,000 with models and place-value strategies, working hundreds, tens and ones separately and regrouping tens or hundreds as needed.
3.NBT.A.1 Use place value to decide which ten or hundred a whole number is closest to, and round to it.
4.NBT.A.2 Read and write whole numbers to a million in digits, words and expanded form, and compare them by place value using >, = or <.
4.NBT.A.3 Round whole numbers up to a million to any place, such as the nearest thousand or ten thousand, by thinking about place value.

3rd Grade Place Value and Rounding Unit Review

3rd Grade3rd Grade Math Curriculum

A review of the unit on place value, rounding and estimating, to go over together the day before the test. Students find the value of a digit, round to the nearest ten and hundred with and without a number line, estimate sums and differences, and check whether an answer is reasonable.
