This is a great packet of word problems for your first grader to work on ten more, ten less (adding and subtracting 10 from a number) without counting.
There are 10 worksheets, each with a variety of problems for students to practice fluently finding 10 more and 10 less AND word problems for them to think through real-life applications and explain their reasoning.
Some of the worksheets also contain some applicable review material including:
identify the place value--tens and ones,
count by 10s,
fill in the pattern (using your knowledge of 10s)
Common core aligned: CCSS.MATH.CONTENT.1.NBT.5
Given a two-digit number, mentally find 10 more or 10 less than the number without having to count; explain the reasoning used.
