Writing numerals: Watch the Numeral Song video on YouTube and have your child practice writing numbers at home.
Play “Beep Number”: Say 3–4 numbers in order, but replace one number with the word “beep.” For example, if you say, “1, 2, beep, 4,” your child responds, “3.” For extra support, invite your child to use a simple number path so he can touch each number as you count.
Count with your child. Place any number of objects (up to 10), such as dried beans or pieces of pasta, in a line. Count them. Then arrange the objects into a circle. Ask: “How many are there now? Did the number of objects change?” Support your child by pointing out that there are still the same number. Repeat for other numbers of objects in different arrangements.
Place 5 objects, such as beans, in a row. Ask your child to add more beans so that there are 6 beans in the row. Repeat for 7 and 8 beans.
As you set the table, count the plates (or any group of items, as long as there are 10 or fewer). Ask your child, “If I set down one more plate, how many plates will be on the table?”
Play Counting Hearts: Separate all the heart cards, ace-10, from the rest of the deck. Scramble the heart cards so that they are not in number order. Invite your child to count the number of hearts that appear in the center of each card. Then have your child arrange the cards in number order and tell how the number of hearts on each card is one more than on the previous card; for example, “Six hearts. One more is seven!”
Ask your child to count and compare objects in your home. “Do you have more toy cars or more action figures? More puzzles or more dolls?”
Play Roll, Draw, Compare. Invite your child to roll a die, count the dots, and then draw the same number of circles. Then ask her to roll the die again, count the dots, and this time draw the same number of squares. Challenge your child to tell whether the number of circles is more than, less than, or the same as the number of squares.
Watch this video with your child to help them develop the understanding that teen numbers have 10 ones and some more.
