Saxon 3 Lesson 31 Extension Game and activity - Adding multiples of ten and estimating sums using rounding
I use this along with Saxon Math Lesson 31, but this could easily be a stand alone lesson.
For the game ou will receive the following:
*40 Matching cards
students will play slap it!! This is a game of speed. They have all of the equation cards face up scattered around them. They then take turns flipping over a sum card from the deck. Everyone races to find the matching equation and "slap it!" First person to slap the correct equation keeps both cards. Next player then flips a sum card. Play continues untill all cards are matched.
The activity is a cut and paste. Students will cut out estimating equation cards. They will decide if the equation is correct or wrong. If it is correct they glue it to the "Correct Course" track. If it is wrong they glue it to the "Wrong Way" track. This activity comes in color and black and white. You could laminate the color veresion and use velcro tabs for the kids to stick the tabs to. Then it could be used again and again!
