## Subtracting 3-Digit Numbers 1

Directions: Using the digits 1 to 9 at most one time each, place a digit in each box to make two different pairs of three-digit numbers that form a true number sentence. You may reuse all the digits each difference. Source: Robert Kaplinsky

## Rounding 2

Directions: Using the digits 0 to 9 at most one time each, place a digit in each box to make the greatest possible three-digit number that still rounds (to the nearest hundred) to 500. Source: Robert Kaplinsky

## Rounding 1

Directions: Using the digits 0 to 9 at most one time each, place a digit in each box to make two different three-digit numbers that round (to the nearest hundred) to 500. Source: Robert Kaplinsky

Directions: Using the integers -9 to 9 at most one time each, place an integer in each box to make two expressions: one that has three or more terms and one that has fewer than three terms. You may reuse all the integers for each expression. Source: Robert Kaplinsky in Open Middle Math

Directions: Using the integers -9 to 9 at most one time each, place an integer in each box to create a polynomial with the least amount of terms. Source: Robert Kaplinsky in Open Middle Math

## Exponents 4

Directions: Using the integers -9 to 9 at most one time each, place an integer in each box to make a value that is as close to zero as possible without being exactly 0. Source: Robert Kaplinsky in Open Middle Math

## Exponents 3

Directions: Using the integers -9 to 9 at most one time each, place an integer in each box to make the least possible value. Source: Robert Kaplinsky in Open Middle Math

## Exponents 2

Directions: Using the integers -8 to 8 at most one time each, place an integer in each box to make the greatest possible value. Source: Robert Kaplinsky in Open Middle Math
