Number story!

WALT make a number story. Sally had 642 lollies for her party. At the end she had 358 lollies left. How many lollies did she eat? This is how you work it out. So you have 642 and 358. Round 358 to the nearest 10, which is 360. To get to that we had to plus 2 so add two to 642 which is 644. So 644-360 = 284. I guess it kind of helps but also takes probably the same amount of time it would take with the original problem. Do you think this strategy helps?
