Exploring Whole Numbers and Money in Saxon Math

This video tutorial covers the basics of Saxon Math for sixth grade, focusing on addition and subtraction of whole numbers and decimals. It explains the commutative and identity properties of addition, demonstrates borrowing in subtraction, and introduces fact families. The video includes several examples and practice problems to reinforce these concepts.

What is the commutative property of addition?

• Multiplying a number by one does not change the number.

• Subtracting a number from itself gives zero.

• Adding zero to a number does not change the number.

• Changing the order of addends does not change the sum.

When adding 345 and 67, what should you do with the digits?

• Align the hundreds only.

• Align the ones, tens, and hundreds.

• Align the tens and hundreds only.

• Align the ones and tens only.

What is the identity property of addition?

• Adding zero to a number does not change the number.

• Multiplying a number by one does not change the number.

• Changing the order of addends does not change the sum.

• Subtracting a number from itself gives zero.

In subtraction, what must be true about the minuend and the subtrahend?

• The minuend must be larger than the subtrahend.

• They must be in any order.

• The subtrahend must be larger than the minuend.

• They must be equal.

When subtracting 5 from 7, what must you do?

• Borrow from the hundreds place.

• Add 10 to the minuend.

• Borrow from the tens place.

• Subtract 10 from the subtrahend.

How do you check your subtraction work?

• Divide the minuend by the subtrahend.

• Add the difference to the subtrahend.

• Multiply the difference by the subtrahend.

• Subtract the difference from the minuend.

What is the inverse operation of addition?

• Subtraction

• Multiplication

• Division

• Addition

Which of the following is a fact family for the numbers 4, 5, and 9?

• 4 + 5 = 9, 9 - 4 = 5, 4 + 5 = 9, 9 - 5 = 3

• 4 + 5 = 9, 9 - 4 = 5, 4 + 5 = 10, 9 - 5 = 3

• 4 + 5 = 9, 9 - 4 = 5, 5 + 4 = 9, 9 - 5 = 4

• 4 + 5 = 9, 9 - 4 = 5, 5 + 4 = 10, 9 - 5 = 3

What is the result of 3675 + 426 + 1357?

• 5480

• 5458

• 5460

• 5470

What is the result of 5.374 - 1.68?

• 3.694

• 3.694

• 3.694

• 3.694
