Learning Outcomes
Missing number sequences → Counting forward within zero to eighteen → Children place skipped numbers in order with fewer counting slips.
Addition equations → Part-whole number sense → Children find a missing addend by checking the total and known part.
Subtraction equations → One less relationships → Children connect neighboring numbers with simple subtraction facts and clearer number sense.
Find the Missing Numbers Worksheet
The Find the Missing Numbers worksheet gives first graders short number rows and simple equations with blanks to fill. Children practice counting forward from 0 to 18, then use addition and subtraction facts such as 4 plus 4 equals 8 and 18 minus 17 equals 1 to find the missing part.
At age seven, many children can count by memory, but skipped spaces can make number order feel shaky. Missing number work matters because first graders need to see what comes before, what comes after, and how nearby numbers help with early addition and subtraction.
Use the page as a short sit-together activity. Start with the 0 to 4 row, then move to 6 to 10, 11 to 15, and 14 to 18. Ask your child to read each full sequence, point to each blank, and say which number belongs before writing. For the equations, ask which number makes the number sentence true.
The worksheet mixes counting rows with matching equation practice, so the page is more than a plain fill-in number chart. The small set of four problems keeps the work short, clear, and ready for shared off-screen practice.
