1st Grade Math

English Counting & Number Sense Kindergarten Readiness 7+ years old

Five-year-olds and seven-year-olds alike can freeze when a number line suddenly has holes in it. This page keeps the task small and clear: fill in missing numbers in four short counting sequences, then solve a related addition or subtraction sentence with one missing number.

The practice is a good fit when a child can count forward by ones and is starting to see how numbers connect in simple facts. The sequences use close-together numbers, including teen numbers, while the equations ask for a missing sum, addend, starting number, or subtracted part. That mix gives useful counting and number sense practice without a long page of problems.

Sit side by side and read each row out loud before writing. If a blank feels tricky, point to the number just before or just after it and ask, “What comes next?” For the equations, use fingers, small counters, or quick marks on scrap paper so the missing part can be checked in a hands-on way.

For a next step, build the teen numbers with place-value practice in the Tens and Ones Build Worksheet, which helps show why numbers like 12 and 15 are made from a ten and some ones. If your learner needs more short, flexible review, the Tens and Ones Number Cards Worksheet gives extra practice reading and comparing numbers before coming back to missing-number problems.

Frequently asked questions

What should my child know before trying this page?

They should be comfortable counting forward by ones through the teen numbers and have some early experience with simple addition and subtraction.

How do we use the missing number rows?

Read the visible numbers from left to right, say the count aloud, then write the numbers that fit in the blank spaces.

How can I help if the equations feel tricky?

Use fingers, small counters, or quick tally marks so the missing number can be worked out instead of guessed.

Why are counting sequences and equations on the same page?

The mix lets a child practice number order first, then use that same counting sense to reason through addition and subtraction.

Should my child finish this independently?

Stay nearby at first because the page switches between sequences and equations, and a simple prompt can keep the work moving.

Can we reuse this printable for review?

Yes, place it in a page protector and use a dry-erase marker, or print another copy for a later practice day.
