Worksheet Description

This worksheet contains a series of numbered boxes, each with a two-digit number and an illustration of a lion, placed in a column. The instructions at the top direct students to write a number that is 10 less than the given number on the left of each box and a number that is 10 more on the right of each box. There are blank spaces provided next to each illustrated box for the students to write their answers. This layout encourages the students to calculate values that are directly more or less than the given numbers by ten.

The worksheet is intended to teach students about the numerical concepts of increasing and decreasing a given number by ten. It helps them understand and practice the basic principles of addition and subtraction within the context of tens. By doing so, students develop a better sense of place value and the decimal system. This type of exercise is also aimed at improving mental math skills, making the students more adept at quickly calculating numbers that are ten higher or lower than a given number.
