A near-20 strategy
For 18 x 7, students can start with 20 x 7 = 140 and subtract 2 x 7 = 14 to get 126. The chart lets them check that result immediately. This approach turns a difficult table into a familiar adjustment.
Notice the even product pattern
Every product in the 18 table is even, and many products are close to familiar multiples of 20. Encourage learners to use those clues to catch errors. If an answer is far from the nearby 20 table product, it is worth checking again.
How to use this printable
The chart is best for targeted advanced practice rather than early memorization. Use it with students who already know smaller even tables and are ready to extend that thinking into larger products with confidence.
Check answers against the 20 table
A helpful activity is to write a matching 20 table product beside each 18 table product. Students can then subtract two groups to reach the 18 table answer. For 18 x 9, compare 180 and 162. Seeing the difference builds estimation skill and helps learners understand why the products are close but not equal.
A common error with 18 facts
Learners sometimes subtract only one group when using a near-20 strategy. Remind them that 18 is two less than 20, so two groups must be removed. The printable helps them compare the adjusted product with the correct answer and see exactly how much the total changes during review.
