100th Day of School Activities 3rd 4th 5th Grade Math Writing | Print and Go, Answer Key

Celebrate the 100th day of school without losing the day.
Your 3rd, 4th and 5th graders know when they have been handed kindergarten work. This packet gives them a 100th Day that is genuinely worth their time: multi-digit place value, a 100-problem fact fluency set, multi-step word problems, patterns and powers of 10, perimeter and area, and a structured “100 years from now” writing project with a rubric.
There are no crowns, no hats, no glasses, no crafts, no cutting, no gluing and no coloring pages in this resource. Every page is a real math or writing task, tied to a real standard, with a real answer key behind it.
What makes this different :

• Every activity is mapped to a named 3rd, 4th or 5th grade standard, and the alignment is printed for you as a chart in the Teacher Guide — 16 math standards and 9 writing standards.
• Genuinely upper elementary. Place value runs to the hundred-thousands and into decimals, not to 100. Fluency is multiplication and division, not addition within 20.
• A complete answer key in its own separate file, so you can send the student pages to the copier without printing the answers.
