In 1993 MR Publishers was launched with the High Frequency series. It seems only fitting to relaunch our website focusing on this series. This series uses the McNally and Hoskins lists of high frequency words and by doing fun activities reinforces the spelling of the words key to language development. Books 1 to 4 are labeled High Frequency books and 5 to 7 are termed Puzzle Books. This series can be used in any curriculum.
