Practice Number +1 with your child. You can use this printable worksheet on which you can try the above steps as well as answer questions using the Number +1 trick.
Carry out the following two steps:
1. Look at the examples below and then try this worksheet to practice more with the Number +1 trick.
Look. These are the same.

2. After completing the worksheets you can use these flashcards to help review and memorize the +1 and 1+ facts.

Review the Doubles above and then try the following three steps:
1. Practice Doubles and Number +1 together on this printable basic facts worksheet.
Look. These are the same.

2. Look at the two different ways above to write the same addition fact. Both ways mean the same thing. Remember this when you try this worksheet to practice Doubles and Number +1.
3. After completing the worksheet, print out and use these flashcards to help review and memorize some of the doubles facts.
These strategies for helping to memorize addition and subtraction facts were developed by Susan
Greenwald, MA Ed. and are taken from the beginning of her Two Plus Two is Not Five workbook.
Susan has written three books on teaching math facts and is a soughtafter
speaker and presenter.
