# Writing and reading decimals thousandths

Ordering Teaching Math with Base 10 Blocks It is my firm opinion that the only manipulatives necessary to teach math are base 10 blocks and fraction circles. I made my own classroom sets of each. Well, I should be entirely honest. My dad, who had a wood shop, made my base ten blocks. Standards Unit Summary In the first unit of Grade 5, students will build on their understanding of the structure of the place-value system from Grade 4 SMP. By the end of the unit, students will have a deep understanding of the base-ten structure of our number system, as well as how to read, write, compare, and round those numbers In Grade 4, students developed the understanding that writing and reading decimals thousandths digit in any place represents ten times as much as it represents in the place to its right 4.

With this deepened understanding of the place-value system, students read and wrote multi-digit whole numbers in various forms, compared them, and rounded them 4. Thus, Unit 1 starts off with reinforcing some of this place-value understanding of multi-digit whole numbers to 1 million, building up to that number by multiplying 10 by itself repeatedly.

After this repeated multiplication, students are introduced to exponents to denote powers of Then, students review the relationship in a whole number between a place value and the place to its left 4. Students also extend their work from Grade 4 on multiplying whole numbers by 10 to multiplying and dividing them by powers of 10 5.

After extensive practice with whole numbers, students then divide by 10 repeatedly to extend their place-value system in the other direction, to decimals. They then apply these rules and perform these operations with powers of 10 to decimal numbers.

Lastly, after deepening their understanding of the base-ten structure of our place-value system, students read, write, compare, and round numbers in various forms 5. Moving forward, students will rely on this knowledge later on in the Grade 5 year to multiply and divide whole numbers 5.

Students will also use their introduction to exponents to evaluate more complex expressions involving them 6. Perhaps the most obvious future grade-level connection exists in Grade 8, when students will represent very large and very small numbers using scientific notation and perform operations on numbers written in scientific notation 8.

Thus, this unit represents an important conclusion to the underlying structure of our number system and opens the door to more complex mathematics with very large and very small numbers.

Assessment This assessment accompanies Unit 1 and should be given on the suggested assessment day or after completing the unit.

## Examples of numbers with thousandths

The central mathematical concepts that students will come to understand in this unit A digit in any place represents 10 times as much as it represents in the place to its right and 1 10 of what it represents in the place to its left.

Multiplying a number by 10 repeatedly or a power of 10 results in the digits shifting to the left. The digits shift the same number of places as are factors of ten. Dividing a number by 10 repeatedly or a power of 10 results in the digits shifting to the right. The digits shift the same number of places as are factors of Comparing numbers written in standard form uses the understanding that one of any unit is greater than any amount of a smaller unit.

Thus, the largest place values in each number contains the most relevant information when comparing numbers. If both numbers have the same number of largest units, the next largest place value should be attended to next, iteratively until one digit is larger than another in the same unit.

When rounding a number, the goal is to approximate the number by the closest number with no units of smaller value e. Vocabulary Literary terms, text-based vocabulary, idioms and word parts to be taught with the text exponent.Fifth Grade Decimals Worksheets and Printables.

Learning the basics of decimals might not be the most difficult mathematical chore. But when it comes to learning how to multiply decimals or convert them to fractions or percents, things can get a bit tricky.

This dot is called the "decimal point". The number above can be read in either of two ways: "thirteen point two" or "thirteen and two tenths". In this case, since we're counting packs of candy bars, the number stands for "thirteen and two tenths packs of candy bars".

These worksheets can help your students review decimals number concepts. Worksheets include place value, naming decimals to the nearest tenth and hundredth place, adding decimals, subtracting decimals, multiplying, dividing, and rounding decimals.

Zero and the numbers 1 -9 make up the set of whole numbers. But not every number is a whole number. Decimals, like fractions, are a way of writing numbers that are larger or smaller than whole numbers.
