Here's a set of weekly word searches using the high frequency words from Scott Foresman Journeys, Unit 4, Lessons 16 - 20. There is one word search per week plus two mixed review word searches for the unit. It would be great to use the review pages as you progress through the series as another way to review past words.
Practicing high frequency words in a word search can aid in retention. The pictures correlate with the weekly theme as well. Hope your kiddos enjoy this way to help them master this important skill!
