Candy heart graphing

Candy heart graphing is the classic Valentine math activity. Kids sort the hearts by color, count each pile and color one box of a bar graph for each heart. Then they find the color with the most and the fewest.

Page 1 of the Valentine’s Day Math PDF is a candy heart graphing page, with no real candy needed. Kids count 20 printed hearts in three colors. Red is plain, pink has dots and purple has a stripe, so a black-and-white print still works.

Then they color the candy heart graph. One box for each heart, starting at 1. Each color gets its own row.

Kindergarten sorts, counts and circles the most and the fewest. 1st grade also finds how many in all and how many more. On the count page, that’s 20 in all and 3 more red than pink.

Some teachers call it conversation hearts graphing. The printed hearts work the same way.

Valentine’s Day math for kindergarten

Kindergarten in February works on number pairs and on adding and taking away within 10. Our Valentine math for kindergarten stays in that range.

Word problems (page 2). Read each one aloud. Your child counts the cards, balloons, hearts or cupcakes and crosses out the ones that go. Then they fill in the number sentence, like 6 − 2 = 4. The sign is printed for them.

Page 4. Write the sum, then draw a line to its heart.

Ten Frame Match (page 4). Each Valentine ten frame has red counters, then yellow, top row first, the way it’s done at school. Your child writes the red, the yellow and the sum, like 4 + 3 = 7. Then they draw a line to the heart with that sum.

Make 10 with Hearts (page 5). Each ten frame is 10 hearts. The first one shows 7 red and 3 yellow, so 7 + 3 = 10. Your child colors some hearts red and the rest yellow, a new way each time. See ways to make 10 and number bonds for more.

Which is longer? (top of page 7). Your child circles the longer of two bands. Kindergartners compare side by side before they measure with units.

Color by number (pages 1 to 3 of the color by number PDF). The heart and the cupcake add within 10. The bee mixes in take-aways. Counting on fingers for every box is fine. Our ten frame printable, addition for kindergarten and subtraction for kindergarten go further.

Adding and taking away within 10 is exactly the range of the app’s addition and subtraction boards. On Luvinci’s Singapore Math boards, each sum sits on two ten frames of pictures, and take-away is one ten frame with the taken-away items crossed out.

Try the free counting board (Counting 1). The ten-frame, addition, subtraction and times-table boards are in the full app. See how Luvinci’s math games work.

Valentine’s Day math for 1st grade

1st grade in February adds and takes away within 20 and works with tens and ones. The 1st grade pages follow that.

Word problems (page 3). Each one is a different kind. Add three numbers, take away, compare, and find how many more are needed. Your child writes a number sentence, then the answer. In 7 + 4 + 6, adding 4 + 6 first makes 10. See word problems for 1st graders for more.

Color by number (pages 4 to 6 of the color by number PDF). The ladybug adds within 20. The cat and the owl mix adding and taking away. Your child meets doubles like 8 + 8, near doubles like 7 + 8 and make-a-ten facts like 9 + 4. The take-aways start in the teens and land under 10, like 15 − 6. See addition for first graders, doubles facts and subtraction for first graders.

Heart Strips (page 6). Each strip holds 10 hearts. Your child counts the strips as tens and the loose hearts as ones, then writes the number. The numbers are 14, 23, 31 and 40. Forty has no loose hearts, so its ones box gets a 0. Our teen numbers guide explains why 14 says the four first.

Measure with Hearts (page 7). Cut out the heart ruler at the bottom. Your child lines up the first heart with the end of the crayon and counts the hearts it covers. Whole hearts only. The hearts touch end to end, with no gaps, and every heart is the same size. Every object on the page lines up to a whole number of hearts, so there’s no half heart to argue over.

The make-a-ten picture (page 8). The helper chart shows 9 + 4, 8 + 5 and 7 + 6, each on two ten frames. Fill the top ten frame first. 9 and 1 more is 10. 3 more makes 13.

Valentine color by number addition

The free Valentine Color by Number PDF has six pictures, three for kindergarten and three for 1st grade, with their answer keys. Each color by number page is a grid of 100 boxes with a sum in every box. The key matches each answer to a crayon. Your child works a box, looks up the answer in the key and colors it. A picture shows up, box by box. Some teachers call it color by sum.

One color mixes different sums, and two boxes side by side never match. Kids can’t copy the box next door. They have to work each one out.

The key prints the crayon’s name next to each swatch, like “13 red”, so a black-and-white printer works fine.

These Valentine’s Day color by number addition pages also make good math coloring worksheets for a quiet table. A whole picture is a lot for a 5-year-old. Work a row or a color at a time.

The color by number PDF, page 7, the first answer key page.

In December, our Christmas color by number pages use the same format.

Valentine math games

The free Valentine Roll and Cover game has two boards of 24 hearts. Kindergarten rolls one die. 1st grade rolls two dice and adds. Its board has every sum from 2 to 12, and 7 shows up most.

• Players: 2. Each player needs a red or a yellow crayon, and you need 1 or 2 dice.
• Roll and find the number. On the 1st grade board, roll two dice and add.
• Color or cover one heart with that number. If none is left, your turn ends.
• When the board is full, or after 10 minutes, count yours. More hearts wins.
• Tip: Try to say the number before you count the dots.

The puzzle PDF, page 1.

The free Valentine Number Order Puzzles are cut and paste. Your child cuts out 10 numbered picture strips, puts them in order and glues them in the frame. A picture appears. Page 1 is 1 to 10 for kindergarten. Page 2 is 11 to 20 for 1st grade. If the picture looks wrong, a strip is in the wrong place.

More dice and card games are in math games for first graders and math card games.

Valentine math centers

Set up four stations and rotate through them over the week.

• Count and graph. The candy heart graph on page 1.
• Roll and cover. Partners on the kindergarten or the 1st grade board.
• Number order puzzle. Cut, put in order, glue.
• Color by number. One picture each, a row at a time.

Laminate the game boards and the heart ruler so they last all week.

If day 100 lands near Valentine’s Day, our 100th day of school printables make a good second set that week.
