When we cut smth in half....1gr.

we have 2 equal pieces

Cutting into 4 equal parts means... 1gr.

cutting in fourth

When ordering objects from smallest to largest you need...1 gr

to compare the numbers

Interpreting bars. 1gr.

The bar goes up to the number..., it means that...

1.00. 1 gr.

The smaller arrow is an hour hand. And the long arrow is a minute hand.


The hour hand is pointing to 1, so the hour is 1. The minute hand is at 12, which means it's exactly 1.00.

10.30. 1gr.

The smaller arrow is an hour hand. And the long arrow is a minute hand.The hour arrow is between 10 and 11, so the hour is 10. The minute hand is pointing to 6, which means 30 min. Whenever he minute hand points to 6, it always means 30 min. So, the time is 10.30

What is ninety-nine in number form? 1gr.

99

What number comes after 119? 1gr.

When we count by ones we are adding 1 each time we go up a number

51+12. 1gr.

When we add 2 digit numbers we start by adding the numbers in the ones place. Then we need to add the numbers in the tens place. The final answer is...

Add 10 to 2 digit number. 1gr.

When we add 10 to a 2 digit number, the only number that changes in our answer is the tens position, and it will always go up by one. Mentally we can add 1 to the number in the tens place to find our answer.

52-10. 1gr.

When we subtract 10 from a 2 digit number, the only number that changes in our answer is the tens position, and it always go down by one. Mentally we can subtract 1 from the number in the tens place to find our answer.

Subtract multiples of 10 from multiples of 10. 1gr.

When we subtract 2 digit numbers, we always start with the ones place, on the right and work our way to the left.

What number is ten and three? 1gr.

ten and three means the same as 10+3

63 > 62 (53 < 55). 1gr.

The > (<) sign means greater (less) than. 63 (53)is greater (less) than 62 (55) because of the number in the ones place. 3 (3) has a greater (lesser) value than 2 (5), which means 63 (53) has a greater (lesser) value than 62 (55).

29 = 29. 1gr.

The = sign means equal. 29 and 29 are the same number, which means they are equal.

18 < 23. 1gr.

When you are comparing numbers with all different digits, you look at the greatest place value to determine which number is greater or less than. In this case we are going to look at the tens place.1 is less than 2 which means that 18 is less than 23.

How many tens are in the number 10? 1gr.

There is 1 in the tens place which means there is one ten in the number 10.

What digit is in the tens place? 1gr.

The tens place is always the second number from the right.

What digit is in the ones place? 1gr.

The ones place is always the first number on the right.

Which math problem below equals 12+8+2? 1gr.

We can add 12+8=20. So the math problem becomes 20+2. Both 20+2 and 12+8+2 equal 22.

The commutative property. 1gr.

The commutative property says that you can add the numbers in any order and still get the same answer. 3+7 and 7+3 both equal 10.

The associative property. 1gr.

The associative property says that you can group a set of numbers in series and still get the same answer. If we group 6+4 to get 10 and then add 3 we get a sum of 13.

Use the unknown addend to subtract.


What can we add to 1 to get 17? 1gr.

1+6=17 or as a subtraction problem, 17-1=16.

To find a missing piece of an addition problem (fill in the blank 2 + ... = 20)... 1gr.

you can take the biggest number minus the smallest number. 20-2=18, which means 2+18=20.

Fill in the blank. 17=...- 2. 1gr.

This question is asking what we take 2 away from to get 17.We can add to find the missing number.

Is this equation is true? 4+5=6+3. 1gr.

Both equations are equal 9. So these two equations are equal each other.
