Web“Investigations in Number Sense and Estimation” is comprised of activities which explore the properties, estimation, and uses of whole numbers and fractions in mathematical and everyday settings. A reasonably level of numeracy is essential to navigating the complexities of the highly technical world in which we live. WebPractice is the best way to become good at estimating, because you need to develop your own "strategies", as different numbers need different methods: Example: 550 + 298: 298 is nearly 300 so an estimate is 550+300 = 850 550 + 248: 50+48 is nearly 100 so an estimate is 500+200 +100 = 800 In one case it seemed easy to change one number and then add.
