If you have 3 quarters and 2 dimes, and your friend has 4 dimes and 1 quarter, who has more money?

You have more money than your friend

You have less money than your friend

Your friend has more money than you

Which value is greater: 5 one-dollar bills or 3 five-dollar bills?

3 five-dollar bills have a greater value

It is impossible to compare them

5 one-dollar bills have a greater value

If you have 12 nickels and your friend has 2 quarters, who has more money?

You have more money than your friend

Your friend has more money than you

I can compare the value of two sets of coins and bills using words (greater than, less than, equal to) and symbols (<, >, =).

Can you make multiple choice 2nd grade questions that cover the following: Demonstrate understanding of the ten-to-one relationships among ones, tens, and hundreds, using manipulatives. (a)  Write numerals, using a model or pictorial representation (i.e., a picture of base-10 blocks). (a)  Read three-digit numbers when shown a numeral, a model of the number, or a pictorial representation of the number. (a)  Identify and write the place (ones, tens, hundreds) of each digit in a three-digit numeral. (a)  Determine the value of each digit in a three-digit numeral (e.g., in 352, the 5 represents 5 tens and its value is 50). (a)  Use models to represent numbers in multiple ways, according to place value (e.g., 256 can be 1 hundred, 14 tens, and 16 ones, 25 tens and 6 ones, etc.). (a)  Use place value understanding to identify the number that is 10 more, 10 less, 100 more, or 100 less than a given number, up to 999. (b)  Compare two numbers between 0 and 999 represented with concrete objects, pictorially or symbolically, using the symbols (>, <, or =) and the words greater than, less than or equal to. (c)  Order three whole numbers between 0 and 999 represented with concrete objects, pictorially, or symbolically from least to greatest and greatest to least. (c)  Round two-digit numbers to the nearest ten. (d)?

CONCEPT OF INTEGERS What are INTEGERS? Integers are whole numbers that describe opposite ideas in mathematics. Integers can either be negative (-), positive (+) or zero. The integer zero is neutral. It is neither positive nor negative, but is an integer. Integers can be represented on a number line, which can help us understand the value of the integer. POSITIVE INTEGERS Are numbers to the right of zero. Are valued greater than zero. Express ideas of up, a gain or a profit. The sign for a positive integer is (+), however the sign is not always needed. Meaning +3 is the same value as 3. NEGATIVE INTEGERS Are numbers to the left of zero. Are valued less than zero. Express ideas of down or a loss. The sign for a negative integer is (-). This sign is always needed. Opposite Numbers/Integers – are the pairs of integers that have the same absolute value or have the same distance away from zero. ABSOLUTE VALUE The distance of a number from the origin (0) regardless of direction is called absolute value. The absolute value of a number is never negative. The symbol for absolute value is two straight lines surrounding the number or expression for which you wish to indicate absolute value. Examples: I 4 I = 4, +4 is read “ the absolute value of 4 is 4 “ I -3 I = 3, -3 is read “ the absolute value of -3 is 3” - I 3 I = -3, means “ the negative of the absolute value of 3 is -3 “ COMPARING AND ARRANGING INTEGERS Integers can be compared using a number line. As you move to the left along the number line, the integers decrease in value. On the other hand, integers increase in value as you move to the right along the number line. To arrange integers in ascending order is to arrange them from least to greatest. This means that when you use the number line, the smallest the integer is to the left of 0 on the number line. To arrange integers in descending order is to arrange them from greatest to least. This means that when you use the number line, the largest the integer is to the right of 0 on the number line. This is read as “nine is greater than negative 12.” This is read as “negative thirteen is less than negative 5.” This is read as “negative eight is greater than negative 18.”
