Teacher's field guide

What Students Need to Do: Students break long words into syllables and meaningful parts, such as prefixes and suffixes. They use letter patterns to read each part and spell the whole word.
What Mastery Looks Like: A student can split basket into bas-ket, read both parts, and blend them. They can spell unhelpful by putting un, help, and ful in order.
Common Misconceptions: Students may guess a word from its first few letters instead of reading every part. They may write helpfull because the suffix -ful sounds like full.
How to Assess It: Have students mark the parts in basket and unhelpful and read both aloud. Then have them turn the paper over and spell both words from dictation.

Lesson moves

Give pairs word cards for basket, sunset, and unhelpful; have them cut at syllable breaks and rebuild each word.
Ask students, 'Why does unhelpful end with one l?' Have them write a sentence explaining the suffix -ful.
Call out unhelpful, rereading, and careless; students race to spell each word and underline its prefix or suffix.
Give students a cafeteria menu; have them choose three long food names, mark the syllables, and read each name to a partner.
