How a bar model can be used to show a subtraction problem? 2 grade

2 Answer

  • lets say that you have 4-2=? you can use a bar model.... 

     {the stars are the bars}
     you have 4 total and now you need to subtract 2
    { i just took away 2 and then you count the bars but in this model count the stars}

    Hope this helps!!! 

  • It can be used because it shows how many of something you took away .
