2nd Grade Unit 2 Math Assessment

Subtraction is the process of taking one number away from another. For example, if you have 5 apples and you give away 2, you have 3 apples left.

Addition is the process of combining two or more numbers to find their total. For example, if you have 3 oranges and you get 2 more, you have 5 oranges.

To find the total, you add the number of items in each group together. For example, if one group has 12 toys and another has 19 toys, the total is 12 + 19 = 31 toys.

'More than' means to add a certain amount to a number. For example, if you have 10 and you have 5 more, you have 10 + 5 = 15.

The result is 351.

Carlos has 46 marbles left.

To find out how many more one number is than another, subtract the smaller number from the larger number. For example, if Elfie has 59 Skittles and Cameron has 33, then 59 - 33 = 26.

Pop Pop has 45 posters now.

A word problem is a math question that is presented in the form of a story or scenario, requiring you to use math to find the answer.
