    Read the lesson
    1. Hi, I'm Pistachio! When we count, we touch each acorn once and say one number for it.
    2. Two apples here, five apples there. Which group has more? Count the bigger group.

    3. Look at the short hand on each clock. The long hand is always up.
    4. Pistachio wakes up at seven o'clock in the morning and goes to bed at eight o'clock at night.

    Adding and taking away

    Read the lesson
    1. Adding means putting groups together. Three apples and two more apples. How many altogether?
    2. Taking away means some go. There were five balloons, and two flew away!
    3. A balance stays level when both sides are the same. Four and one on this side, five on that side: 4 + 1 = 5.
    4. A trick for big sums: 8 + 5. First fill the ten: 8 + 2 = 10. Three are left over, so 10 + 3 = 13.
    The three questions
    1. What is 4 + 3? (answer: 7)
    2. Six birds sat on a branch. Two flew away. How many are left? (answer: 4)
    3. Which number makes ten? 7 + ? = 10 (answer: 3)

    1. To count money, start with the biggest coin and count on: ten, fifteen, sixteen, seventeen.
    2. Count by fives: five, ten, fifteen... It's much faster than counting one by one!
    3. The apple costs seven. Five and one and one make seven. Not one more, not one less!
    4. When the long hand points down, it is half past. The short hand sits halfway between nine and ten: the market opens at half past nine.
    The three questions
    1. Which coins make eight? (answer: (picture))
    2. Count by fives: 5, 10, 15... What comes next? (answer: 20)
    3. Which clock shows half past four? (answer: (picture))

    1. Multiplying is adding equal groups. Three rows of four stars: 4 + 4 + 4, or 3 × 4.
    2. Counting in tens is the secret door to the ten times table: ten, twenty, thirty...
    3. Turn an array around and the answer stays the same: 2 × 5 and 5 × 2 are both ten. Learn one fact, get two!
    4. A missing number is a riddle: 5 × ? = 35. Count in fives until you reach 35. That's seven fives!
    The three questions
    1. Which picture shows 3 × 4? (answer: (picture))
    2. What is 4 × 5? (answer: 20)
    3. 6 × ? = 30 (answer: 5)

    Fraction pizzeria

    Read the lesson
    1. A fraction is part of a whole that is cut into equal pieces. This pizza has four equal slices. One slice is one quarter.
    2. The bottom number says how many equal slices the whole has. The top number says how many we mean. Three slices of eight are left: 3/8.
    3. Half or quarter? The more slices you cut, the smaller each slice. One half is bigger than one quarter, and two quarters make one half.
    4. To find one third of twelve, share twelve into three equal groups. One group is one third.
    The three questions
    1. Which pizza has three quarters left? (answer: (picture))
    2. Which fraction is the biggest? (answer: 1/2)
    3. What is one quarter of eight? (answer: 2)

    Captain's market

    Read the lesson
    1. Giving change means counting up from the price. The toy costs 7 and the customer pays 10. Count up: eight, nine, ten. That's 3 change.
    2. When the long hand points to three, it is quarter past. When it points to nine, it is quarter to the next hour.
    3. A budget is the money you can spend. With 20 you can buy the book and the apple: 9 + 6 = 15. Adding the cake as well would be too much.
    4. Be a balance detective. The balance is level, so both sides weigh the same: ? + 2 = 5. The mystery block weighs 3.
    The three questions
    1. A pencil costs 6 coins. You pay with 10 coins. How much change do you get? (answer: 4)
    2. Which clock shows quarter to three? (answer: (picture))
    3. The balance is level: ? + 4 = 9. What does the mystery block weigh? (answer: 5)
