Product description
From the author
This is a Make Numbers to 20 Worksheet.
This is a 2 page printable for each student to complete.
There are 5 columns on each of the pages.
The columns consist of making 11 through making 20. There are 11 problems for students to complete in each column. Each problem follows the same sentence frame with a student having to complete the second number to make the equation true.
At the bottom of the second page, there is a space for you to score this worksheet. A space to record elapsed time appears before the score; provide a separate timer.
In order to accurately time track, you can:
-Have a stopwatch running and displayed on the board for students to write down their own time when they finish. By doing it this way, you can have an entire class of students complete their worksheets at the same time. This will only work if students are old enough to understand tracking time. A great way to implement this is to model it many times with practice pages.
-Complete this worksheet in small groups, a few students at a time, with the teacher or a paraprofessional. By doing it this way, you can give students attention and write their times down on your own. Making sure you have accurate times for students will allow you to implement this same worksheet repeatedly to measure and track growth.
This can be a great data tracking tool if you are looking for something to assess fact fluency for addition and subtraction within 20.

Teaching tips & learning objectives
Learning objectives
Find a missing addend or subtrahend in an equation within 20.
Use addition and subtraction relationships to make a target number.
Teaching tips
Start with one column and discuss how its equations share a result.
Have students identify the operation before finding the missing number.
Use the timer and score line only when timed practice suits the lesson; untimed work is also possible.
Skills covered
Fact fluency within 20 — students solve 110 missing-number addition and subtraction equations, one column per target number from 11 to 20.
Missing-addend/subtrahend reasoning — each problem gives two of three equation parts (a starting number, an operation, and the result) and asks students to find the third.
Timed self-assessment — the built-in timer and score line let students track their own speed and accuracy across all 110 problems.
Good to know
Questions teachers ask about this resource
Do the columns use only addition, or subtraction too?
Both. Each column mixes addition and subtraction problems that total the same target number — the Make 11 column, for example, includes 16 − ___ = 11 alongside 0 + ___ = 11.
