Missing Numbers? This is a classic skill that they are working on for both kindergarten and first-grade math classes.
As you build to first-grade skills, you should be able to count from 1 to 100.
Missing Numbers for First Graders
This worksheet covers a few different concepts – first of all, working in a sequence. There is only ONE number of each set of ten in a row. You little student has to fill in 90 blanks out of 100,
What are Missing Numbers?
Missing numbers are the numbers that got missed in the given series of numbers with similar differences among them. The process of writing the missing numbers is termed as finding similar changes between those numbers and filling their missing values in their specific series and places.
This activity is a great way to introduce number order!
You can show them how row two all start with a “1”, how row three all start with a “2”, etc – to cover the teens, twenties, etc.
You can teach multiplication too!
Let’s start with the 9s. Start at 9, and then go down a row and backward for 9 times 2 (18). Go down a row and backward again for 9 times 3 (27). You can see the diagonal pattern for the rest of the numbers.
The same principle works for the number 8 but you go backward two spaces as you drop down each row. You can see 8 – 16 – 24, etc
Teach even and odds!
You can shade in or have them color in every other square – to form a checkerboard pattern of sorts. Now you can clearly see the difference between odd numbers or even numbers.
Use it as a number line
First grade uses number lines in both addition and subtraction. This is a simple counting squares concept. Start at #4 and add 3. You count up one-two-three squares and are at #7. 4 plus 3 equals 7.
It works the same way in reverse, for subtraction.
You are only limited by your imagination!
That is one thing I learned in Indiana at the Connor Prairie living museum that we visited a few years ago. I learned the pioneer version of the math pyramid.
I have looked everywhere to find a video to show it to you but can’t find one. The way it was used to teach addition, subtraction, multiplication, fractions, and division was simply brilliant. Simple. And Brilliant.
You can see it in this video that talks about Conner Prairie, but they don’t cover how it works.
