正确答案：C. 6 o’clock

考点认读钟面：几点整 · Telling time: o’clock

思路：长针指着 12，短针指着 6，是 6 点整（6 o’clock）。
Think: The long hand points to 12 and the short hand points to 6. It is 6 o’clock.
小提醒：长针指 12 时就是“几点整”，看短针指着几。
Tip: When the long hand points to 12, it is o’clock. Look at the short hand.

正确答案：A. 10¢

考点钱：买东西找零钱 · Money: finding change

思路：他只有 50¢，只买得起 40¢ 的西瓜。50¢ − 40¢ = 10¢。
Think: He only had 50¢, so he could only buy the 40¢ watermelon. 50¢ − 40¢ = 10¢.
小提醒：先找出买得起的东西，再算找回多少钱。
Tip: First find what he can afford, then work out the change.

正确答案：B. the boy in the middle (on the high step)

考点比较高矮：起点不同时比较 · Comparing heights from different starting levels

思路：三个男孩的头顶一样高，但站的地方不一样高。中间的男孩站在最高的台阶上，脚下垫得最高，所以他本身最矮。
Think: Their heads reach the same line, but the middle boy stands on the highest step. He needs the most help to reach the line, so he is the shortest.
小提醒：比高矮要从脚底量到头顶，不能只看头顶。
Tip: Measure from the feet to the head, not just where the head is.

正确答案：C.

考点规律：重复的图形规律 · Patterns: repeating shape pattern

思路：规律是“圆形、长方形、长方形”重复。第二组已经有了圆形和一个长方形，所以下一个还是长方形，而且和前面的长方形一样大。
Think: The pattern is circle, rectangle, rectangle, again and again. The second group has a circle and one rectangle, so the next shape is a rectangle, the same size as the others.
小提醒：图形的大小也要和规律里的一样。
Tip: The size of the shape should match the pattern too.

正确答案：B. the bottom pencil

考点比较长短 · Comparing lengths

思路：两支铅笔的橡皮一端对齐，再看另一端谁伸得更远。下面那支更长。
Think: The eraser ends are lined up. The bottom pencil goes further, so it is longer.
小提醒：比长短时，先把一端对齐。
Tip: To compare lengths, line up one end first.

正确答案：A. size

考点形状：按大小或形状分类 · Shapes: sorting by size or shape

思路：A 组和 B 组里都有同样的四种形状（半圆形、三角形、圆形、长方形），只是 A 组的都小，B 组的都大。所以是按大小分的。
Think: Both sets have the same four shapes. The shapes in Set A are small and the shapes in Set B are big. So they are sorted by size.
小提醒：先看两组里的形状一样不一样。
Tip: First check if the two sets have the same shapes.

正确答案：B. 7 + 2

考点加法：10 以内的加法 · Addition: adding within 10

思路：一辆一辆算：3 + 5 = 8，7 + 2 = 9，8 + 2 = 10。只有 7 + 2 等于 9。
Think: Work out each one: 3 + 5 = 8, 7 + 2 = 9, 8 + 2 = 10. Only 7 + 2 makes 9.
小提醒：每个算式都算一遍再选。
Tip: Check every sum before you choose.

正确答案：B. False

考点乘法意义：“几个几”的读法 · Equal groups: reading "4 fives"

思路：图里有 5 个篮子，每个篮子 4 个蛋，是 5 个 4（5 fours），不是 4 个 5（4 fives）。
Think: There are 5 baskets with 4 eggs in each. That is 5 fours, not 4 fives.
小提醒：“4 fives”是 4 组、每组 5 个。先数组数，再数每组几个。
Tip: "4 fives" means 4 groups of 5. Count the groups, then count how many are in each group.

正确答案：B.

考点乘法意义：几个几（等组） · Multiplication: equal groups

小提醒：先数有几组，再数每组有几个，两样都要对。
Tip: Count the groups first, then count how many are in each group. Both must match.

正确答案：C. 57

考点数数：十个一组数到 100 · Counting: counting in tens and ones to 100

思路：每一排数一数：前 5 排各有 10 支，是 5 个十 = 50；最后一排有 7 支。50 + 7 = 57。
Think: The first 5 rows have 10 pencils each, so that is 5 tens = 50. The last row has 7. 50 + 7 = 57.
