Starting at zero, + means move to the right and - means move to the left. Start at 0 and move 20 units to the right. Second move 5 more units to the right (20+5=25) so you are at 25. Third move 32 more units to the right (25+32=57) so now you are at 57. Now move 3 units to the left (57-3=54) so you are at 54. Finally move 98 units to the right (54+98=152) so you are at 152. Thus 20+5+32-3+98 = 152.

After playing these games online continue playing the games at home without the help of your computer. For example, play the "cookie game" at the kitchen table using real cookies, apples, etc. A great way to play the "wrong numbers game" is to play school with your preschooler.

Votes:0 Addition and Subtraction Facts to 20 The basic addition and subtraction facts are all the combinations of 1-digit numbers (2+2, 6+9, 8+4, etc.) and the corresponding subtraction exercises (18-9, 7-4, etc.). (See the fact chart at the end of this page.) To you, these are probably automatic. You don't need to think about them because you've memorized the answers. That immediate command is what you're striving to teach your students. There are a variety of strategies that can be used to figure out or remember facts. Addition Properties: The zero property states that zero added to any number is the same as the original number. The commutative (or order) property states that the order of addends does not matter: 3 + 4 = 4 + 3. Subtraction Rules: There are two rules for using zero in subtraction Read More Go to Site mathSURF: Reading for Math--Grade 1, Chapter 2, Questions Votes:0 Story pictures Instructions Hippo Harvest Picture 1 Harvest time is Henry's favorite time of year.
