**Math in My World**

Example 1

The bank book shows how much money was added to Bart’s account each time he visited the bank. How much money did Bart have after each trip to the bank? Complete Bart’s bank book.

The circled digits show which place’s value changed each time. So, Bart had $ ___ after the first trip, $ ____ after

the second trip, and $____ after the third trip.

Bart added some money to the $1,676 he already had in his account. He now has $1,686. Complete the number sentence to show how much he added.

$1,676 + ____ = $1,686

Answer:

The circled digits show which place’s value changed each time. So, Bart had $576 after the first trip, $ 676 after

the second trip, and $1676 after the third trip.

Bart added some money to the $1,676 he already had in his account. He now has $1,686. Complete the number sentence to show how much he added.

$1,676 + 10 = $1,686

Explanation:

$575+ $1 = $576

$576 + 100 = $676

$676 + $1000 = $1676

$1,676 + 10 = $1,686

Example 2

Patrick kept track of the miles his family traveled on a trip. Each time they stopped, he wrote down the miles from the odometer. Patrick noticed a pattern in the numbers he wrote. Describe the pattern.
