Estimation is not as hard as it sounds. Especially when you learn our estimation chant. Estimate Means (Cheer) Estimate means... Round Then Add And Round Then subtract WHAT? Round Then add And round Then subtract And soon it will mean... Round And Multiply and multiply and multiply

To estimate just follow these 2 steps: 1. Round each number to the largest place 2. Then add, subtract, or multiply the numbers together

Rounding To round underline the largest place and then focus on number to the right. If the number is 1,2,3, or four, the number will round down. If the number is 5,6,7,8, or 9, the number will go up. Example: 49 rounds to 50 42 rounds to 40 891 rounds to 900 843 rounds to 800

To remember how to round learn our rounding song. Rounding Numbers (To the Army Chant) Rounding numbers is so fun! Repeat We will do it 'til we're done!
