Grade 4 questions
How many 4th grade math skills are included?
35 skills for grade 4: 32 content skills plus error analysis, a mixed review set and a placement screener. Each comes at three levels, which makes 105 printable packs and 620 pages.
Which Common Core standards does grade 4 cover?
The grade 4 packs practice these codes: 4.G.A.1, 4.G.A.2, 4.G.A.3, 4.MD.A.1, 4.MD.A.2, 4.MD.A.3, 4.MD.B.4, 4.MD.C.5, 4.MD.C.6, 4.MD.C.7, 4.NBT.A.1, 4.NBT.A.2, 4.NBT.A.3, 4.NBT.B.4, 4.NBT.B.5, 4.NBT.B.6, 4.NF.A.1, 4.NF.A.2, 4.NF.B.3, 4.NF.B.4, 4.NF.C.5, 4.NF.C.6, 4.NF.C.7, 4.OA.A.1, 4.OA.A.2, 4.OA.A.3, 4.OA.B.4, 4.OA.C.5.

Support uses smaller numbers, a worked example and a shorter page. On Level is the grade-level expectation. Challenge moves the unknown, adds steps and asks students to explain, with a rubric on the key.
Can I buy only grade 4?
The library is sold as the full Grades 1-5 set for $97, which suits teachers who differentiate across grade levels, homeschool families and tutors. The free sampler lets you check the format first.
Each pack practices the part of its standard named in its title. This is practice and review, not a full grade 4 curriculum.
