Why practice spelling in 8th grade if there is spell-check?

Tests and in-class essays are written by hand, and spell-check does not flag a real word typed in place of the right one. These words are the ones that get marked most in high school.

What makes these words hard?

Each one breaks a pattern the student already trusts. Supersede is the only common word ending in -sede, and conscientious keeps the science spelling inside it (con-scien-tious). Naming the break is what makes the spelling stick.

The kind of words you'll practice

Say each word, then cover it. Write it twice from memory, and check your spelling.

Each word sits beside a fold line with two write-on lines: read it, cover it, write it from memory twice, then uncover and check.

Every print pulls a new set of words at this level, so a make-up test or a second sibling gets a different mix.

What's on an 8th grade sheet

8th grade sheets draw from 41 words, 8 to a page. None of these words are on 7th grade sheets.

Cover and write. Say each word, then cover it. Write it twice from memory, and check your spelling. 8 words per page.

Every version prints on US Letter or A4, with a word list on the last page.

How to teach this

Most of these words break a rule on purpose: supersede ends in -sede, liaison has an i on both sides of the a, minuscule starts with minus. Have your student say the reason out loud before writing. A spell-checker will catch these in typed work, so give extra practice to the words your student writes by hand, like on tests.

Watch for: These words are not hard everywhere; each is hard in ONE spot. Naming the trap before writing points a spotlight at exactly the letters that bite. Sounding out is the enemy on this page: these are the words English spells against its own sound rules, which is precisely why everyone misspells them.
