HELP! Apprentice just started Level 3 CCLD and no learning materials

[DearDanielle]

Hi :)
I started my job as an apprentice in a nursery 3 weeks ago and got signed up to my course with tsw last week. My assessor VERY briefly went through unit 1 with me because i was at work and didnt have much time. After getting home and looking at the questions i'm feeling extremely overwhelmed!
I've asked my assessor about learning materials like textbooks or if she could even point me in the direction of any websites but all I've been told is "any level 3 childcare book and there's plenty online" ....this has led me here for help!
I'm a mother of 4 that hasn't worked since going on maternity with my first child 11 years ago!

What books or websites helped everyone else?

These is the first question in my first unit

Understand the expected pattern of development for children and young people from birth - 19 years.
1.1 Explain the sequence and rate of each aspect of development from birth - 19 years.
1.2 Explain the difference between sequence of development and rate of development and why the difference is important.

Any help with be very extremely appreciated!
