Multiplication and Division - Divide by 10 - Planning

In Year 4, students are introduced to the concept of dividing by 10 as part of their autumn term learning in Multiplication and Division. The lesson plan includes a series of activities designed to reinforce this mathematical operation. Key resources such as place value counters, a place value grid, and Base 10 blocks are utilized to visually demonstrate the process. The lesson begins with a starter activity that asks students to recall their previous experience with multiplication by 10 and predict the inverse operation when dividing by 10. The initial class teaching input encourages children to understand that when dividing by 10, digits move one place to the right, making the number 10 times smaller. This is practiced through hands-on activities where students use manipulatives to visually see the shift of digits and the consequent new number formation.

Further learning is facilitated through the use of Dienes/Base 10 blocks, where students physically divide each block by 10 to comprehend the reduction in value. For instance, dividing 160 by 10 is illustrated by breaking down the 100 and 60 into their smaller counterparts, 10 and 6, respectively. The lesson continues with the use of counters and a place value chart, allowing students to see the effect of division on larger numbers, such as turning 60 into 6 or 450 into 45. The lesson concludes with Activity 3, which incorporates a place value chart with a decimal point to extend understanding to 2, 3, and 4-digit numbers. Students are encouraged to reflect on their learning, discuss the skills they used, identify any challenges, and make a 'pinkie promise' to remember the key concepts from the lesson. Differentiated worksheets cater to varying levels of proficiency, from 'Working Towards' to 'Working at Greater Depth', ensuring that all students can engage with the material at an appropriate level of challenge.
