Teaching addition strategies: goodbye standard algorithm. if you’re a 1st or 2nd grade teacher, you should definitely be saying see ya later to the standard algorithm. listen, i’m not saying you can’t show it to your students. but i am saying we’re doing our students a disservice if we’re not helping them develop deeper strategies for.

2 3 Digit Addition Strategies Simply Creative Teaching Writing Mini The goal of this addition math strategy is to make the problem easier to solve! students will make a friendly number (10, 20, 30, 40, etc.) by moving a few ones from one number to the other number. 6.) standard model. the last strategy is probably the one seen most frequently, but i prefer to spend more time on the first five strategies. Sep 23, 2019 transitioning your students from basic addition to 2 3 digit addition can be tough sometimes! there are five 2 3 digit addition strategies i focus on in my classroom. these strategies do not focus on the standard algorithm. if you’re looking for 2 3 subtraction strategies, you can read all about them over on this post!…. On the first day of teaching 3 digit addition strategies, i use a place value addition mat so students can physically practice manipulating the numbers when solving problems. in this example of 104 188, students build out each addend with base ten blocks (or in this case… snacks!). then, they add up the ones first. Materials needed: paper, pencil, post it notes and scissors. start with ones place and write the sum on the post it note. cut apart the post it note between the tens and ones. place the tens post it half on top of the tens row in the addition problem and find the sum. 3. break it up method.

Addition land is a simple board game played similar to candyland! students draw a card from the stack, solve the problem, and move to the space on the game board that corresponds to the color of their card. the different colored cards have different types of problems on them. for example, all of the the pink cards have basic facts to 20.
