=__**//COUNTING//**__ has three types:=

__ **//COUNT FROM://** __ Beginning at 13, count backwards for a 5 count, and the number you end up with is your answer. For example, 13 then 12 - 11 - 10 - 9 - 8 (5 count) and your answer is 8. Number sentence: 13 - 5 = __8__

__ //**COUNT UP TO:**// __ Beginning at 5, count up to 13, and count the numbers you counted. For example, 5 then 6 - 7 - 8 - 9 - 10 - 11 - 12 - 13, then counting from 6 to 13, you counted 8 numbers, so your answer is 8. Number sentence: 5 + __8__ = 13

__ **//COUNT DOWN TO://** __ Beginning at 13, count down to 8, and count the numbers you counted. For example, 13, then 12 - 11 - 10 - 9 - 8, then counting from 12 to 8, you counted 5 numbers, so 5 is your answer. Number Sentence: 13 - __8__ = 5

=__**//FACTS//**__=

__**//FACTS//**__ uses standard math facts to derive the answer.

13 - 5 = ?

5 = 3 + 2

13 - 3 -> 10, then 10 - 2 = 8

Number sentence: 13 - 5﻿ = 8
