I have combined my SLAM DUNK ROUNDING program with 60 task cards for a complete package to ensure all your students master rounding to the nearest 10. The additional task card bundle extends rounding into the thousands.
The original program comes with 20 TASK CARDS and 20 MATHS RIDDLES which have answers provided and can be added to a maths centre as an independent activity. The addition of the 60 task cards bundle gives you 80 differentiated task cards, rounding off 2, 3 and 4 digit numbers. Combined with the 20 maths riddles, you have 100 task cards that can be differentiated to the needs of all learners.
I find there are two areas of potential difficulty with rounding. Some students don't 'get' the pattern of rounding by number so I have a little jingle that appeals to some students. The rhythm helps them remember when to round down and when to round up.
The other problem is identifying the tens numbers that the given number comes between and that's why I use a number line and teach students to mark the half-way point. Once they practise using these task cards, they are ready to perform this process mentally. Some need more practice than others and that's why there's so many task cards. Students don't have to do them all.
You will save by buying the bundle. I have the cards laminated and each students has their own answer sheets. Students who master the task cards are ready for the MATHS RIDDLES. These really make them think and will appeal to your faster learners.
