The tens digit is 1 less than the other factor. (The sum of the product’s digits is 9.Write out the multiplication sentences and answers on the chalkboard (9 x 1 = 9, 9 x 2 = 18, and so on) and ask students to find a pattern and discuss what they find. Have the students count by 9s on the number chart.When I look at the multiples of both 2 and 5, I see that they all end in zero.What patterns do they notice? (The multiples of 5 end in 5 or 0).Have students count by 5s, circling the multiples of 5 with a blue marker on their number charts.What patterns do they notice? (The multiples of 2 are even and always end in 0, 2, 4, 6 or 8.).Ask them to examine the numbers carefully. Have students count by 2s, shading multiples of 2 yellow on their hundred chart.Display the Teacher’s Chart an overhead transparency, or copy it onto the board.Introduce key vocabulary: multiple, factor, product, double.Teacher: Teacher’s Chart of multiplication patterns to be printed as an overhead transparency or copied onto the board. Student: Crayons or markers, Hundred Chart, Doubles Worksheet, Independent Practice Worksheet, Multiplication Table. This lesson can be divided into two or three smaller lessons, each lasting about 20-25 minutes. understand and use the zero property for multiplication and the property of one as a factor in multiplication.develop computational fluency by exploring patterns in multiplication for products involving one-digit factors.Students will learn to use patterns and property theories as strategies for recalling those facts. This lesson enables students to begin the process of mastering multiplication facts. Slowing down to type numbers into a calculator will actually cause them quite a bit of frustration-so a little hard work upfront will prevent problems in the future.Please Note: this material was created for use in a classroom, but can be easily modified for homeschooling use. Additionally, multiplication lays the foundation for division, algebra, and many other concepts that will come down the road as they get older. (Think of shopping, bill paying, taxes, investments, loans, etc…). Multiplication is a necessary life skill, and your children will need to calculate daily mental math with speed to make quick decisions. This is actually a great question! With the world at our fingertips, and the calculators in our pockets, why even teach multiplication facts to begin with? For me personally, as a homeschooling mom, the answer was simple: LIFE. However, in more formal learning programs, students begin multiplication table memorization in the 3rd grade.
Students as young as kindergarten can start practicing their x10 facts as soon as they can count to 100, because they are able to recognize simple number patterns on the hundreds chart. Learning multiplication times tables doesn’t have be for older students only.
