Addition and subtraction: Watch the Khan Academy videos below. The first is a link to Grade 3, which will be good revision.

https://www.khanacademy.org/math/cc-fourth-grade-math/cc-4th-add-sub-topic

 

 

IXL: Work through addition starting at B1 (or wherever you are up to). To consolidate, you may want to start with revising the same concept from Grade 3 first.

Similarly, with subtraction, start at C1 (or wherever you are up to) and continue. Again, you may want to start with revising the same concept from Grade 3 first.

You may use this optional template as a starting point:

 

Introduction: Name, why they are well known and why you chose them

Early life-any significant events that shaped them

Famous/popular books: overview/any common themes

Later life/ why we remember this author/are they still alive? /what are they are doing now?

 

Please do this on a Google Doc. and save it in your Language Folder so that your teachers can view it.
