In order to differentiate math instruction, I've found it so easy to program my own math worksheets for addition and subtraction with two digit numbers using bean sticks. Students are working on 1.NBT.2: Understand that the two digits of a two-digit number represent amounts of tens and ones. It helps with 1.NBT.4: Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.
I searched for a basic set of bean stick/bean singles that I could paste into a Word document/Publisher document and came up empty. I created this graphic set to make it easier to program my own flashcards, worksheets, etc. Each graphic (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, & 100) is its own file, so it's just like clip art.
I hope you can get some use out of this!
