This is a place value concepts math review slideshow for 4th grade. I use this for a review before the NYSED Math State Test. This contains a review of the place value chart, ten times more/less than an amount, different forms (standard, expanded, word, unit), comparing, rounding, and subtraction. The problems on the last slide align with the purple Ready Book aligned to the Next Gen. standards, published in 2023. Feel free to use if you have the book or edit the last slide and out in whatever
