10. Read and write the numbers
Let's make some fruit cakes for the party!
Mum: Mmm ... We need fifteen eggs, thirteen apples and twelve bananas. How many eggs do we have?
Nina: Let me see. We have four eggs.
Mum: We need eleven more. What about apples and bananas?
Nina: One, two, three ... We have eightapples. But we have no bananas.
Mum: OK! Let's go to the shop together.

five; more
解析：
1. 第一空：妈妈说需要13个苹果（thirteen apples），妮娜数后回答有8个苹果（eight apples），所以还需要的苹果数量为13 - 8 = 5，用“five”表示。
2. 第二空：根据上文妈妈问“我们还需要11个鸡蛋”（We need eleven more）的句式，此处对应苹果的情况，应填“more”，表示“还需要5个苹果”（five more apples）。
答案符合三年级下册“数字”单元内容，通过简单减法计算缺失数量，并用“数词+more”结构完成句子。
