Writing numbers to 1000

The first instance of the Writing numbers to 1000 exercise is under the Early Math Math Mission. This exercise continues practice on the naming scheme and grouping patterns in numbers up to 1000.

Types of problems
There is one type of problem that shows up in this exercise:
 * 1) Select the correct representations: This problem starts with a number (usually three digit, but there are a few two-digit numbers mixed in) and then asks the student to select correct representations from a multiple select list. Some are in words, some are by hundred, tens and ones, and some are as addition problems.Kw1.png

Strategies
This exercise has only one problem type so as soon as it can be understood and predicted, this exercise is easy to make accuracy and speed badges.


 * 1) There will always be three correct answers among the four multiple select options.
 * 2) The written selection and the addition problem selection are always correct.
 * 3) Among the grouping selections, the correct one will be the one that starts with hundreds (or tens in the case of two-digit numbers) since these are the largest groups on numbers less than 1000.
