Hi, my son goes to the 5th grade in Russian School of Math. The tuition is crazy high at almost $200 per month.
I have been searching online for a book that would cover the math topics mostly Algebra. So far he has learned
Solve for x, speed,time,distance,input and output tables,Pemdas,number stories.
I was not given the curriculum and I do not think the school will give me so If any of you understand what comes next you will probably knows the gist of the curriculum.
Is there a good home schooling book that covers all these topics so I can teach him at home.
I am looking for a book that also has practice questions including the answers .

Thanks.
