About This Lesson
To teach students where to place the decimal point for adding and subtracting decimals, have them place Frosty the Snowman's 3 buttons on the paper. Draw a line under the 2nd button. The 3rd button is for the answer. They write the problem around Frosty's buttons and then add or subtract the numbers. Remind them of the place values of the numbers to the left and to the right of Frosty's button.
This teaches the process only not the deep understanding of place value of decimals for addition and subtraction.
