A selection of worksheets based on one my class' favourite stories to get children using a number square to find 1 more/less and 10 more/less than a given number!

• The first sheet gets children to find 1/more or less, followed by a simple word problem.
• The second sheet involves finding 10 more/less, followed by a simple word problem.
• The third sheet gets the children to find 1 and 10 more/less than a given number and is followed by a word problem that begins to develop reasoning skills.
Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.
Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.
Write numbers from 0 to 20. Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects).
Count forward beginning from a given number within the known sequence (instead of having to begin at 1).
Count to 100 by ones and by tens.
