A complete, image-rich 4-lesson mini-unit perfect for late October wrap-up or assessment prep. Students practice place value to the millions, multi-digit addition & subtraction (standard algorithm + fluency ladders), intro multiplication strategies (arrays, area models, partial products), and decimal foundations (tenths/hundredths with number lines & money links). Includes mini-posters, manipulatives, exit tickets, mixed review, and answer keys so you can teach tomorrow with zero prep. 4t
